1985 – “PAL” (a.k.a. “H.E.N.R.I. VIII”) the Robot – Douglas Trumbull (American)

Above image sourced from Richard Steele .

Doug Trumbull, who directed the 1972 sci-fi cult film "Silent Running" and was behind the design of the drones later designed and patented a remote-controlled character called “PAL” which was first used in the Showscan film LET’S GO for the Toshiba Pavilion at Expo ’85 in Tsukuba, Japan. Closer robotic performance was achieved via a high-tech version of Japanese Bunraku puppetry, performed from below by master puppeteer Bruce Schwartz. PAL was the inspiration for Johnny 5 in the movie "Short Circuit" (1986),  directed by Badham. Steven Spielberg saw the film at the Expo and took note of "PAL's" builder, and passed the information onto Badham who engaged Allard for the robot construction in "Short Circuit". .

Patent number: D292223
Filing date: May 17, 1985
Issue date: Oct 6, 1987

The Robot Controller [below] was first used as a prop in the Showscan film LET’S GO (Live Action, 19:00 minutes) a story of a very special friendship that develops between a boy and a robot, for the Toshiba Pavilion at Expo ’85 in Tsukuba, Japan. As stated by Trumbull, "this gizmo may have interesting future applications as a human-computer interface."  

Eric Allard was a young effects wizard who made the robot. The robot effects were achieved with a rod puppetry techniques. For those who don't recognise the name, Eric Allard also built "Number 5" for the movie "Short Circuit."  The appearances between the two are remarkably similar.

Here is a text extract from the magazine Cinefantastique (July 1986) on the making of No. 5 :

"…but the job went to 30 year-old Eric Allard, whose few prior credits included DRAGONSLAYER (the full-scale dragon claw); BRAINSTORM (the destruction of the automated production line) and most importantly, a Showscan short titled LET'S GO, which featured an anthropomorphic robot named Pal.
Pal was a four foot tall tubular creation on a motorized, wheeled base that had been designed by Don Guzay1. Trumbull had come up with the idea of combining radio-controlled servo mechanisms with the techniques used to manipulate large Japanese rod puppets (Jim Henson's Muppets occasionally use these techniques, as well). Trumbull and Allard, along with assistant Barnaby Jackson and puppeteer Bruce Schwartz, worked out the details. Built over a 10-week period, Pal was still crude, but the technique showed great promise.
 Based on his work with Pal, and a recommendation by Steven Spielberg, Allard got the script to SHORT CIRCUIT on a Friday and was asked to prepare a bid. Monday morning, he returned with a lengthy proposal breaking down every shot in the film in which robots would appear, outlining how each shot could be accomplished. …"

Interesting to note that the above article says Don Guzay designed PAL, although Doug Trumbull owns the design patent.

1  David Buckley informs me that Don Guzay, as spelt in the article, should actually be Dan Gouzeé, a noted illustrator and artist.

Email On Sep 19, 2012 between Reuben Hoggett( and Barnaby Jackson,

RH:  Hello Barnaby, ….. I've recently posted an article on the Trumbull Pal robot from the Showscan move "Let's Go". See here . I know it's going back in time a fair way, but I believe that Pal is very significant in the history of robots in more ways than one. From different articles it appears the key players behind Pal were: Doug Trumbull, designer Don Guzay, builder Eric Allard, puppeteer Bruce Schwartz, and yourself. As mentioned on your own website, you are the one who is credited with the construction and on-set operation of the robot. I'd be interested to hear your view of the Pal story, if you wouldn't mind sharing it with me.

BJ: Hi Reuben,

I worked with Eric Allard on the construction of PAL, and really "learned by doing" under his supervision. He would sketch parts for me to machine, and then slowly, part by part PAL came into being.

I traveled to Germany with PAL for the shooting of "Let's Go" and made modifications and enhancements to the robot to support the needs of the production. There were two on-set configurations for PAL. His top half came off so we could attach the puppeteering rig to Bruce's head and hands. For wide shots he was a remote control driving robot. On set Bruce Schwartz brought him to life using smooth compound moves. I performed PAL's eyes and eyebrows with servo remote control.

The idea for PAL was Doug's and Don1 made a range of drawings based on Doug's direction. When a final drawing was approved, we began construction. I would say the whole team participated in the design of PAL, but Doug had the original vision for PAL that we all tried to follow. A patent really refers to the idea, which was Doug's.

Eric Allard really made PAL. He loved that robot, and I think there was a bit of a father son relationship between man and machine. In fact all of us from Doug on down developed a strong bond with PAL, that I'm sure still remains to this day. I was lucky as a young man to learn so much and to be allowed to work at a high level with Doug, Eric, Don1 and Bruce.

PAL was a film robot, so his personality was a function of the performance and the moments that the filmmakers decided to include in the final film. You can really see Doug's vision for PAL, when his mechanical hand rests atop the boy's, and the simulator takes them up into space…
 1  David Buckley informs me that Don Guzay, should actually be Dan Gouzeé, a noted illustrator and artist. My fault for giving Barnaby the wrong but similar name to recall.

PAL wearing an American Boy Scout scarf, which appears in one of 'his' movies. PAL has an operational mouth now, which resembles a split table tennis ball.

For those who are interested, those two servos are Tonegawa Seiko SSPS-105 Servos and the Linear activator at the bottom is a SKF linear activator wth D24 pancake motor. The SSPS-105 is also used on Johnny Five for his shoulders and two of  the same SKF activators are used for the tip toe feature of  Number Five.

PAL also did a stint on The Wizard as "H.E.N.R.I. VIII" with David Rappaport. Images from fansite here.

"H.E.N.R.I. VIII"  stands for Hazardous EnviroNmental Robotics Intelligence of the 8th prototype.

A few images show the single steering wheel at the rear, not at the front as per the patent design. My friend David Buckley, a robot builder, suggests the single trailing wheel is a preferable and more practical approach to a mobile platform.

Where is "PAL" now?

Richard Steele, avid Johnny 5 collector, says that "PAL" is still with Eric Allard. He also adds that there were a number of J5's built for both "Short Circuit" movies, and one of those [the fifth one], along with the telemetry suit as used in the second movie, is now located in the United Kingdom. He has a good home and is very much looked and cared for after having being restored to fully working capacity. 

In 2005 PAL was still with Eric Allard and J5! – Thanks Dave Everett.


Eric Allard mentions that PAL was used for a few TV programs. In Allard's CV, there are the shows he mentions:

                                                                TELEVISION CREDITS
Production                                                        Studio                         Position

Lois & Clark TV Episode                        Warner Bros. TV     Robotic Supervisor

Ab.- Minded Professor TV Episode       Disney TV               Robotic Supervisor

Does anyone recall or have seen any of these to confirm PAL's appearance?

1971 – “Silent Running” Drones – Doug Trumbull, Don Trumbull, Paul Kraus & James Dow (American)

Early Concept Drawings

Drone Concept drawings.

The credited people behing the Drones are Doug Trumbull, his father Don Trumbull who at least built the arms, Paul Kraus & James Dow.

In an interview on the construction of "Phil", the robot from Heartbeeps, "Phil"'s creator was Jamie Shourt, who says he was also involved in the creation of the Drones. Shourt was a business partner of Trumbull's earlier on, so there may be some truth to the statement.

The Amputee Actors

[I derived which actor was inside each Drone by the images below.]

Drone #01 [Dewey} (Grey) was manned by Mark Persons.

Drone #02 [Huey] (Orange) had 2 different actors/amputees at different times. Most likely distinguished by the slightly different bases employed by each. Steve Brown was first and had a narrowed base most of the time. Chery Spark's has a stepped protrusion.  Both were long cases when compared to the others. It  appears as if Cheryl replaced Steve sometime through the filming.

Drone #03 [Louie] was manned by Larry Whisenhunt, aged 16.

Most of the time, the robot arm was a dummy, to save weight. This is most evident when the forearm is almost flush with the drone's body.

Interview with Doug Trumbull by Castle of Frankenstein magazine (Issue #19) 

T….As everyone said, the only human on board Discovery was HAL. I didn't see it that way at all. Futurity does not necessarily denote inhumanity. The character that Bruce Dern plays is warm, funny, and fallable. I decided to work with that human element.
CoF: The Drones contribute to that warmth.
T: It's curious about the drones. If you were to see the film again, you'd see that most of the humanity of those machines is a result of your own projection. They're programmed metal; if you need a companion, you simply punch a button. If you need a surgeon, you change its function—very simple.
CoF: But there's obviously a great
amount of emphasis on the drones to humanize them.
T: Part of SR's theme is the relationship between Dern and his drones. It's not 2001 — machinery isn't malevolent. They're simply tools. Look, here you have this guy who's a murderer. He's killed three of his friends. He's alone on a vessel that's as isolated from the rest of the population as possible. He begins to crack, to feel his conscience. So he creates companions by reprogramming the drones. An interesting thing.
CoF: There was a photo article in
T: Yes. It was a very cruel thing. Cold. We tried to stop it. Tried to stop them printing it. So, we used amputees. So what? They're people. That's a horrible cliche, but it's true. They're human beings.
CoF: How did you get the idea for using amputees for the drones?
T: When I was in London, working on 2001, I saw a film called FREAKS. Have any of you seen it? Well, there's one little fellow; he's very handsome, and neat — he's dressed in a tuxedo and a bow tie. Only, from the waist down, he isn't there. So, here's this remarkable, beautiful guy, with this amazing agility,
leaping and running on his hands through the room, jumping up on chairs, etc. And not once did you feel horrified. You're amazed and respectful at his adjustment. That impression stayed with me when it came time to cast the drones. I knew what I wanted.
CoF: Wasn't there any resistance to the idea of using these people?
T: Only from the studio. Producers are the most unpleasant groups of humans on the earth. They said we could use midgets, or children, but not amputees — we had to fight very hard for that. And it worked.
CoF: You say "kids." How old were they?
T: Fifteen to twenty-two. Four of them worked with us. One was a girl, one was a black kid from Watts who leaped off a moving train. The others were congenitally handicapped. This was, literally, the only job these people could get.
CoF: How did they like the work?
T: They loved it. They all made a lot of money and spent it like crazy.
CoF: For non-professionals, they certainly did a fantastic job.
T: Yes. They were a great help.
Speaking of ideas, and things just happening — do you remember the bit when Huey is outside the ship, waiting for Bruce to give orders? If you look closely, you'll see he's tapping his foot.
Between takes in the filming of SILENT RUNNING, the "secret" of the Drones locomotion is revealed as Cheryl Sparks, one of the amputees, has a chat with Bruce Dern.
That was a spontaneous thing. He, the actor, was bored, so he tapped. We filmed it.
CoF: When Dern comes into the rec' room, two of the drones are waiting. One drone has his back to the door. Drone facing Dern taps drone facing away on shoulder. Drone turns. Was that bit in the script?
T: It all comes back to what we were saying about things just happening. These guys were cooped up in six-inch thick plastic suits. They could barely see. The only way they could communicate was by yelling and banging each other on the shoulder. One day I saw them doing this on the set, and I thought, "Great !", and we put it in.
CoF: …(more interview, but not about the drones)……..

Drone Arm and Grippers

The end effectors are interchangeable. As the Drones are service robots, they are supposed to be capable of doing many things with their one arm. 

I notice on this wonderful 2004 drawing by Eric Kristiansen that what I believe to be tools in tool bays, he calls them 'sensors' or 'sensor arrays' .

Most of these additional tools [assuming they actually are tools] appear to be dummies. The real gripper in the tool bay is most evident in this still.

The Drone arms were designed and built by Don Trumbull, Doug Trumbull's father, who had a history in Special Effects, starting with "The Wizard of Oz" (1939) .

In reality there appears to be only 1 interchangeable end-effector that is carried by the drones, and that is the most common one seen here. The general-purpose robot gripper has a pincer action with flats on each finger. When it is not located in the arm, it is in its recepticle in the tool bay on the front of the body [in reality, the pneumatic lines to the gripper prevent disengagement of the gripper to the wrist/arm]. 

Here's a series of images [below] that shows Drone #02 hooking up its wrist connector to the gripper. The geometry of the arm and the location of the end-effector would have limits where connection to tools/end-effectors could occur.

The 4-quadrant pink light is, in my opinion,  the Drone's "eye". Most noticeable during the game of poker when "Huey" look's at his own cards and the lights turn on and off.

A black and white pic showing the arm just after it hooked up the gripper to its wrist connector from its home in the tool bay.

The other interchangeable end-effectors (or tools, as the case may be) seen in action include long-tanged fingers, hooked (or clawed) fingers, rotary high-speed saw, welding electrodes, and possibly a screw-driver or a probe of some sort.

Long-nosed fingers holding bandage roll.

For the operation, the arms were manipulated by off-camera crew, including Doug Trumbull himself.

Another view of the high-speed rotary cutting tool directly inserted into the wrist adapter. I don't believe it would have been operational in this shot, as these tools are air powered [brand of air-tool not yet identified].

As revealed in "The Making of …", Dern was worried that a remotely controlled arm, if a mistake was made, would "cut off his leg". A bit of an overstatement, but nevertheless, a dummy leg was made up, and Doug himself manouvred the arm (off-camera and seen in b/w image above) by holding it with his own hands to cut the pants.

Selectred transcript from "The Making of 'Silent Running'"

Narrator: Scott Beach

DT   and one of the most important things that I had as an idea was the idea of doing the drones.
Narr: The Drones –   In the story their job is to  relieve humans of boring routine maintenance on the spaceship. In science fiction, robots have often been the bad guys  Molevolent semi-human contraptions sneakily computing ways to take over. But Doug Trumbull wanted to show that these man-made devices are only what the're made and absolutely under  human control.

DT:  The idea was to find a human being that you could deal with as an actor but their wouldn't be necessarily  shaped like a human being. Why just put a big plastic or rubber suit over a man and say that's a robot? Do something that  defies an audiences capability to understand how it was done. We wanted to be totally be non-Anthropomorphic in appearance.    No face, no eyes,  nothing that is glaring out, nothing that's necessarily symetrical like a human being. The working robot models that we use in the picture  are the prototypes. in that we   did a lot of drawings, a lot of visualisations of what we wanted  But when on paper we got to a point where the shape was right if we could see that the shape was going to work the way we wanted  we just started making moulds out of  wood and vacuum forming styrene plastic over the wooden moulds and fitting them together and making the design in such a way that it could be altered to fit each individual person inside.

Larry Whisenhunt, aged 16
Steve Brown 15
Mark Persons 22
Cheryl Sparks 17. All double amputees, all very talented.

Another narrator: What's it like inside that suit?

CS: Well, Its quite comfortable and everything.   It's awkward when you're trying to walk and stuff.

Narr: Is there a special feeling that you have towards people once you're inside that outfit – you start taking on a feeling of a robot.

CS: You do kinda, yeah
Especially the scene when the dome? is about to blow-up It's like I was really there and in a few seconds everything was really going to blow-up.

Narr: What do you like to do? What are your activities?

CS: Horseback riding, swimming, surfing, water skiing,   any outdoor sports. And fishing.

Narr: It took several technicians to build the drone models

Narr: This is Paul Kraus

PK  Well, Of course, the first problem was trying to find people that would fit in them . After that just measuring, getting an awful lot of human Dimensions then after that the main problem was material. Because the biggest structural problem that we found was that they had to be lightweight. We had to keep them under 20 lbs, which we did, they run out just under 20lbs.

[Bruce Dern talking on set for a bit.].

Narr: The Drones are programmed to do their job with little or  no human attention, but in the poker sequence is was man-to-machine. Bruce Derm played the part of Freeman Lowell. He programmed the drones to play cards.

[Richie was operating Drone #02’s arm in this scene]

BD: One of the keys to the film is the fact that are that they are not mechanical. The fact that here's a guy all by himself. He's looking at a box…… has no eyes, no mouth, no ears and yet it's alive, and there's something that I respond to as an actor, as a human being, and as a character in the film and that's what's its really all about. Somehow the fact that any little box or machine  I've always been scared of machines anyway, that can move around the floor and stuff. I saw a movie once,  "The Glass-Bottomed Boat", it was terrible movie but Rod Taylor and it  had a little machine that cleaned up his kitchen, you know, that he pressed a button it came… [new part 2 from Youtube missing transition]

…packing everything there and it scared the shit out of me, man. But I respected it, you know and I thought, that, well, he should talk to it, you know.

[card playing scene].

no more on drones until…

The Making of Silent Running Pt3
There was a constant problem with the manipulator arms on the drones. They kept not working. The crew tried just about everything imaginable. [The] radio control worked fine in the workshop, but on the ship the metal bulkheads caused interference, and the system wasn't reliable.
Then they tried this sort of pneumatic system. Nothing. Finally they came up with a mechanical system that did just well enough so that the shooting could go on.

Doug T-"for everone of those shots there was just numerable takes… constant re-shooting to get the arm to hit the right position.. constantly had to do cutting, and cutting, and cutting, because you couldn't get the arm to do a complex motion and really  do anything in any single one take.

A lot of those close up shots of the manipulator arm working when the arm is cutting away the pant leg on Bruce's leg  I'd get in there and work the thing myself because I wanted it to cut a certain way, but Bruce absolutely wouldn't be in the suit.

BD: The only time I was really scared was they have that little whirring cutter on  that one drone. but it worked of a pump so that when the air is shot through there [whirring noise]like that and it starts going  cutting on my pant leg on my thing there there and if it ever slipped it would've cut my leg right off, you know.

Narr: talks about prosthetic leg.

 [Please contact me for corrections to the above transcript] 

After quite a bit of research I managed to determine whether or not the grippers were custom built or commercially made.  Having a manufacturing plate on the side of the gripper was a give-away, but unfortunately I was unable to read the plate. A bit of good fortune in that whilst researching my next post (on Joshua from "Demon Seed") I recalled a 1981 advert that had a similar gripper. I'm 99% sure the Drone grippers and this gripper are the same, pending variances in the fingers. The grippers are B.A.S.E.(TM) Robotic 2-fingered grippers manufactured by MACK Corporation,  Flagstaff, IL, USA. They are still in business and the grippers still feature in their pdf catalogs here and here.

The pneumatic rams were manufactured by Bimba Manufacturing Company, Monee, AZ, USA. They are stainless steel and have brass air-hose fittings. 

As at August 2012 one of the arms is for sale by The Prop Store. See a set of wonderful photos ideal for the replica maker. Below is only one of them.

Side view with scale.

Art Andrews put up a high-res picture of the Pneumatic Drone arm as seen at the Prop Store booth at San Diego Comic-Con 2012 here.   The display card suggests it was the only operational arm used in the film. When one sees the movie this is clearly not the case. At least 2 arms are seen, particularly the surgery and tree planting scenes [see below].

Side-view showing mounting of arm to body.

Other commercial Parts used on the Drones 

In another post on the web, we get informed that the headlight is branded "CARELLO" , and the original part number is 06.390.816. The dimensions of the light are 5-1/2" x 2-7/8".   

A possible inspiration for the Drone arms – the Case orthotic arm. 

Other than home-builts, no production robots were anthropomorphic, certainly not the industrial robots of the time. However, there were a few orthotics and prosthetics being computerised at the time.  One of the very first is the Case arm, developed at Case Institute of Technology c1965. It's been difficult to find a good picture of this arm, but in this poor picture here you can see the similarities between it and the Drone arm. Being anthropomorphic, it has a shoulder, elbow, and wrist, offering 5 degrees-of-freedom. The Case arm is also pneumatic, and has padding around the cylinders which has a resemblance to the red-plastic arm covers on the Drones.  


VERSATRAN – The other Robot in "Silent Running"

The "billiard's" playing robot is actually an AMF Versatran industrial robot.

Regarding "Silent Running", for a 1972 movie, the Versatran was still considered a state-of-the-art industrial robot.

Two interchangeable end-effectors are shown, a gripper for loading/depositing billiard balls, and a pneumatic "cue" to strike the ball (below). The standard two-fingered Versatran gripper picks up a B.A.S.E.(tm) 3-fingered gripped to deposit the balls. Another small continuity error in that when picking up the B.A.S.E.(tm) gripper, the 2 pneumatic lines are not attached, but then magically appear in the next shot (see above).  Also in the above image is the AMF Versatran name/logo, as well as the controller on the left. 

The control panel in the background is a real and actual point-to-point Versatran control panel,  used to program the various movie sequences. Although portrayed as "thinking for itself" , this robot would have to be choreographed and programmed via the point-to-point controller.

See separate Versatran post here

Related Trivia: Doug Trumbull later designed and patented a remote-controlled character called “PAL” which was first used in the Showscan film LET’S GO for the Toshiba Pavilion at Expo ’85 in Tsukuba, Japan. Closer robotic performance was achieved via a high-tech version of Japanese Bunraku puppetry, performed from below by master puppeteer Bruce Schwartz. PAL was the inspiration for Johnny 5 in the movie "Short Circuit" (1986).

The Robot Controller was first used as a prop in the Showscan film LET’S GO (Live Action, 19:00 minutes) a story of a very special friendship that develops between a boy and a robot, for the Toshiba Pavilion at Expo ’85 in Tsukuba, Japan. As stated by Trumbull, "this gizmo may have interesting future applications as a human-computer interface."

Eric Allard was a young effects wizard who made the robot. The robot effects were achieved with a rod puppetry techniques. For those who don't recognise the name, Eric Allard also built Johnny 5 for the movie "Short Circuit."  The appearances between the two are remarkably similar.

PAL also did a stint on The Wizard as H.E.N.R.I. VIII with David Rappaport. See fansite here.

"Silent Running's" drones inspired "Star Wars" R2-D2

According to a August 14, 1981 Hollywood Reporter article, Universal sued Twentieth Century-Fox, claiming that the droid "R2-D2" in Star Wars was an infringement upon the design of drones Huey, Dewey and Louie. Judge Irving Hill of the U.S. District Court in Los Angeles dismissed the case before trial, however, stating that "no one has a monopoly on the use of robots in art," and that the robots in question were not similar. Universal appealed the decision, but the Court of Appeals also dismissed the case.

Interesting to note that 3-CPO was based on Maria the robot from Fritz Lang's 1927 movie Metropolis, and that Don Trumbull worked on "Star Wars" and was also one of the designers of the Drones. There are certainly a lot of similarities, in terms of size, noises instead of voice, and a utilitarian function between the two. Did Don influence the design of R2-D2?

Los Angeles Times – Dec 5, 1977

……….The drones. by the way, proved to be director George Lucas' inspiration for his own stubby robot, R2-D2, a fact that he admitted to [Doug] Trumbull when he approached him about contributing to "Star Wars." Trumbull, however, turned down the assignment because he did not want to repeat himself by returning to another space opera…………..

Found on the internet is the original concept behind "Silent Running". See here[server now gone Aug 2015]

Another unsung trivia nugget unearthed by greg moss.

This week I’d like to reveal a little-known piece of trivia to do with one of my favourite films of all time – Douglas Trumbull’s 1972 SF eco-fable Silent Running.

This film had a massive impact on me as a third grader and no doubt planted the seed for my lifelong appreciation for ecology. The film screened as a midday movie on television and my favourite teacher Mr. Till (who, looking back, could probably be referred to as a bit of a hippy) sat the class down to watch it. I don’t know about the rest of the kids, but for me, it was a seminal experience.

And one which I will be eternally grateful for.

It was only later, in high school, that I learnt the ecological aspects which had such an impact on me weren’t actually present in Trumbull’s original story idea which was primarily about the relationship between the Lowell character and the drones.

The shooting script was ultimately credited to Deric Washburn & Steve Bochco and Mike Cimino (who subsequently directed The Deer Hunter).

In an interview with Trumbull, published in the August 1978 edition of Fantastic Films magazine, Trumbull outlined his original story …

“I wanted to elaborate the story of that relationship [between Lowell and the drones]  showing how the machines changed from simply doing their job to their anthropomorphization into real characters. I wanted to show what a dead end it is but also what a wonderful thing it is because of the output of emotion.”

“Around the beginning of 1970 I met [producer] Mike Gruskoff. He said “Come up with a story and maybe I can sell it for you”. I worked out a short story and we made a deal with Universal Pictures”.

“That story involved contact with with an extraterrestrial life force. It was the basic story of some ET’s who are travelling around and who detect this guy who is totally alone, totally isolated. He’d be the guy to make contact with. Here’s a guy out alone. He likes being alone. He likes that job. He’s totally alone in the ship with his little robots whom he has no relationship with at all. He’s getting a little bit old for the space program and he gets the kiss off from the company. They say “You’re being retired with congratulations and everything … and we’re really glad you’ve done such a good job for us.” He says, “But I don’t want to go back. I like it out here alone. I don’t want to go back to Earth. I just want to be left alone.” Here he is with a big old clunky space freighter that is going to be decommissioned anyway. It’s a big piece of shit and he says, “Well, I’ve always sort of wanted to go out exploring.” He decides to steal the ship and he enlists the help of the drones. He reprograms them to help him out and respond to him. They tear out all the communications equipment, throw it out into space, paint the whole ship totally black so no one can see it jet off. He’s constantly threatened by the fact that he could be pursued, that the authorities will be out looking for him. He’s a space pirate, and he’s having the time of his life. He sees a little blip on the radar screen which is the only thing he’s kept functioning. He sees something approaching his ship, and figuring the only safe way is to stay out of sight, he goes into the silent running mode. He turns off all the lights, all the electricity, anything that emits any kind of detectable emission. The ship’s all black and everything. He tries to be absolutely cool and not make a noise and not do anything. No light, all black. And he just waits and this blip gets closer over a period of a week he’s sitting there watching it and he’s sort of cracking up, watching this radar scanner. The air is getting really foul and the oxygen is getting really thin because he hasn’t got the air conditioning on, and finally just before it gets there he passes out. Then there’s this really neat sequence that happens.

It’s all seen from just his room. He’s in the control room. He’s all alone, completely conked out. He’s in that room and it’s dark and you just hear this big clunk of two ships coming together. Then you hear the air lock open and footsteps going down the hallway. You hear things going by. You hear someone turning the knob of the door. It’s all dark. And the camera is just cruising around. By this time with all the things turned off the ship’s in weightless condition. There are books and junk floating through the room and you just sort of see shadows moving. You go back out and the door shuts and the electricity comes back on, and he wakes up a few minutes later with fresh air and everything. The ET’s are gone. He looks around and finds all the places where they pried doors open. He sees all the manifestations that some weird being was on his ship and had saved him by turning the oxygen and stuff back on for him. Finally he realizes that one of the drones is gone. The drones are constantly transmitting television pictures to the three little screens in the control room. He figures that by setting up a little impromtu tracking system he can find out where the drone’s signal is coming from. He sets up his antenna and gets this little, weak signal. He tunes it all in and he’s super adjusting it, increasing the gain and everything, and finally he gets a picture from the drone and it’s a view of our own galaxy receding away from the point of view of another ship that’s got some weirdo shape. He starts talking to the drone. “Find a hatchway. Get inside the ship. Find out what the ship is like.” He’s making first contact with extraterrestrial beings by remote control. The drone hustles around and finally finds a door and gets inside. He’s really getting close. The drone is inside. Then there’s another blip on his radar screen and he realizes it’s the cops. The rest of the film is a big race against time for him to try to make contact before the cops break in. They’re saying “Come out you goddamned space pirate.” He won’t come out. He’s got the door bolted and everything. On the ET ship the drone is getting closer and closer until finally it goes to the right room and opens the door. You see some really weirdo electric man, or something really super duper – he sees the ET and just at that moment, just as he’s finally made that contact, the door to his room just goes Whammo! This cop comes in and wipes out the whole room with a big flame thrower and he’s instantly incinerated. The camera cuts to the drone. It’s just sitting there, not knowing what to do, confronted with these extraterrestrials. The drone just takes his little arm and reaches inside his little body and pulls out a little photograph that he’s carried around with him. It’s a picture in which the hero posed with the three drones, like a little family portrait. The drone holds the photo up to these extraterrestrials and the movie ends like that.”

Greg Moss is a film school graduate with a background in directing music videos and is currently seeking representation as a screenwriter. He likes right-brained people, feeding the cat and watching genre movies.

The ship itself was said to be inspired by the Expo Tower from EXPO '70 in Osaka. The architect was Kiyonori Kikutake (1928-2011). See pic below.

Paul Van Hoeydonck (born 1925) is a Belgian printmaker and painter. He studied both archeology and art history in Antwerp, Belgium. His first one man exhibition took place in that city in 1952. During the following years van Hoeydonck both lived and worked in Belgium and in the United States. His art is now included in the collections of leading museums in Europe and America.

He also created "Fallen Astronaut", an aluminium statue about 8.5 cm long that is the only piece of art on the Moon.

The Apollo 15 crew had agreed with Van Hoeydonck that no replicas of "Fallen Astronaut" were to be made. After mentioning the statuette during their post-flight press conference, the National Air and Space Museum contacted the crew asking for a replica made for the museum. The crew agreed under the condition that it was to be displayed with good taste and without publicity.

1967 – “Kaliedophonic Dog”, “Rosebud Annunciator” (1969) – Stephan von Huene (American)


Interview with John Gaughan who restored "Tap Dancer".

Dorothy Newmark*

* Computer artist living at 820 Hermosa Drive, N.E., Albuquerque, N.M. 87110, U.S.A. (Received 22 November 1969.)

Interviewer's note—Stephan Von Huene was born in Los Angeles, California in September 1932 and is currently residing there at 1336 Sutherland Ave. He studied art at Chouinard Art Institute in Los Angeles and at the University of California at Los Angeles [1-4]. He teaches at present at the California Institute of the Arts in Valencia, California.


Newmark—'Tap Dancer' (1969) is your latest audio-kinetic sculpture. Do you feel it is the culmination of a period in your work?
Von Huene—All of the sculptures that were in my 1969 exhibit at the Los Angeles County Museum of Art were the culmination of a certain direction; that is, the use of biomorphic forms activated by a player-piano mechanism and accompanied by music.

`Kaleidophonic Dog' (1967) was my first machine to operate successfully. A dog is  lying on its back with parts of it moving, accompanied by sounds of a wooden drum, 8 organ pipes and a xylophone. Used in the machine are five loops of 2 in. tape with perforated programs that move along a tracker-bar arrangement. The pneumatic system causes parts to move and the drum, organ pipes and xylophone to produce sounds.
N. Would you describe the mechanism you use?
V. H. The basic part of it is a valve that acts like a switch and a tracker bar over which rides a perforated tape. When the perforations in the paper tape line up with holes in the tracker bar,it turns on the valve switch and allows air to be pumped out of
a small bellows that has a hammer attached to it. The hammer may hit a drum or it may operate another small bellows that opens a palate valve connected to one or more organ pipes. The organ pipes are operated by an air blower. The perforated tape, or several of them, can be rewound automatically; the system can also be operated during the rewinding phase. If anyone is interested in the details of the system I use, I would be glad to provide them.
N. What led you to use the player-piano mechanism ?
V. H. I was at first simply interested in finding out how it worked. I found that the 11.5 inch player-piano paper strip was too wide for my purposes and now use a 2 in. paper tape. I punch holes in the tape at random or with a specific program of sounds in mind. I would like to make it possible for anyone to prepare the tapes, so they would produce sound combinations to suit themselves—either ordered sound sequences, which are, I suppose, what we call music or haphazard sound arrangements.

N. Would you describe your most recent piece, `Rosebud Annunciator' (1969).
V. H. It has an overall appearance of early California architecture, heavy and oak-furniture-like, an influence that stems from a very romantic part of my early life in Pasadena, California. On top of the machine is a leather rose, made up of sixteen sections that can be inflated and deflated. Then, on each side there is a post with an inflatable, deflatable leather sphere in a box on top of it, connected by tubing to the pneumatic system. The center part is made of a large xylophone with twenty-four notes, two cymbals, a drum and an octave of reeds.
N. I note that 'Rosebud' is 7 ft high and 8 ft wide. What led to the center part being so large, was it the xylophone ?
V. H. The xylophone determined the width but it was the pneumatic system underneath it that brought about the rather large height.
N. Tell me how you incorporated inflatable parts with sound producing elements in this audio-kinetic sculpture.
V. H. First, I made the rose as a relief in wood. Then I formed over it separate pieces of leather. Later, I mounted these pieces so that the assembled form could be activated by air pressure. The motion of the rose and the sounds are controlled by the player-piano mechanism and the roll, both when it unwinds and rewinds. The roll rewinds faster than it unwinds in this machine. While the roll unwinds the animation of the rose and the spheres is slow, monotonous, ceremonial, then on the rewind there is a fast jumble that gives the feeling that the machine is falling apart amidst a din of sounds.
N. Has anyone commented on the sounds emitted by 'Rosebud' ?
V. H. In the fall of 1968, I was asked to exhibit `Rosebud' in the Electromagica Exhibition in Tokyo. That was an international exhibition of art objects using electricity. It was organized by the Japan Electric Arts Association. At the show I met a Chinese scholar who said that he noted with interest that my machine was playing Japanese music. I explained to him that I had based the music, more or less, on Bach's 'Two-Part Invention' and the beat was related to some of the music composed by Stravinsky. Perhaps this combination sounds Oriental to some. To me the beginning part sounds a little like the music I heard in Vera Cruz, Mexico. The end, as I said before, is a jumble of sounds, nevertheless, the complete program has, I believe, a certain kind of consistency which I enjoy.
N. Did it take you a long time to complete `Rosebud' ?
V. H. Approximately two years—'Kaleidophonic' Dog' took three years. 'Washboard Band' and 'Tap Dancer' each took me only six months to complete.

N. Would you give some details on 'Tap Dancer' and 'Washboard Band' ?
V. H. 'Tap Dancer', as you can see in the photograph, consists of the legs of a man below the knees. The shoes are a bit odd looking. The legs oscillate in clockwise and counter-clockwise directions, while the toes of the shoes go up and down. The toes are connected pneumatically to wood blocks inside the supporting box to make tapping sounds against the top of the box. The sculpture is programmed by a tape loop that lasts about 4 minutes and it automatically plays over and over.
`Washboard Band' consists of two major elements. The taller column supports an ordinary laundry washboard upon which beat four sticks. There is also a sliding piece that moves
horizontally, back and forth, to produce a rasping sound. Above the washboard is a cymbal and a cow bell, which are struck periodically. On the top of the shorter column, there is a plastic box containing reeds that vibrate when air is blown past them. (The air also moves leather strips above the reeds.) The sculpture is programmed by two tape loops of different length. With each revolution of the loops the program on each tape phases into a new relationship.
N. Do you have some new ideas you want to apply to your audio-kinetic sculptures?
V. H. Yes. I want to handle the whole sculptural lay-out in a different, simpler way. Also I want to use different sound-producing objects that produce less well-known sounds. I'll still use wood and leather for some moving parts, as I find them satisfactory materials—I used wood and leather even before I started to make audio-kinetic sculptures. When I became interested in player piano mechanisms and organ pipes, I found they also had wood and leather parts. I believe I have improved the old systems for sucking and pumping air both to activate pneumatic parts and to produce various kinds of sound. When I made figurative sculpures in the past, I used wood covered with leather rather than with paint. You may find it surprising that I also used bread instead of wood because I like its tactile, sensual qualities.
N. But is bread sufficiently durable?
V. H. I made it durable. After the bread formed, I dried it and covered it with resin. Sometimes, I used fresh dough and allowed the rising of the dough, caused by the action of yeast, to fill a desired shape. I enjoyed working with a material that has life-like properties. I became quite obsessed with bread for a while. I wrote stories on paintings I had seen that seemed to me to be all bread. People seemed to be all bread. It was as if they became what they ate. No doubt, a very primitive attitude on my part. Why make images of people out of stone, of metal? Why not make them out of bread or leather? Certainly, these materials are most appropriate for making images mimicking people.

Current art is often made of absences: absence of purpose, absence of meaningful connection between things, absence of material and conceptual definition, absence of elaboration, absence of professionalism, absence of uplifting values, absence of personal identity, absence, even, of pathos. Artists seem intrigued by these gaps, these meta-states that leave things blankly self-evident or connected in perfunctory series like the numbers in a traffic count.
Stephan von Huene's art is one of presences. Not simply the physical presences of well-crafted objects, inventive and focused for eyes and ears; but, rather, 'magical' presences. Here are beings, surrogates for ourselves, who perform for a time and then are mute until requested to act and speak again. Oracles. They communicate in crypto-syllables from a language just beyond translation. They emit hoots, moans, clicks, beeps and breathy sounds, punched out on hidden paper tapes and run by vacuum sweeper motors. I've seen them in their mahogany dusk. Lights shine from their insides. Ceremonies.
For instance: A one-man band without the man who is the band, mechanically having become the band, plays for itself in an empty room. A white rose. Presence of the absence.
And: A vaudeville team in some bar in 1920 where for a nickel in a slot they'll rag, rattle, tonkle, scrape and blow. Washboard face with cowbell feather. Guardian Nickelodeon. Very serious. Mutt and Jeff at attention.
And: Enormous shoes of the clubfoot dandy, tapping away nifty twist of the hard-tipped toes under heavy folded cuffs. Insidious dance to the music we refuse to hear so we listen to the tappety tap of the man we won't see. Tappety 
And: Erect wooden columns, alone, in pairs, threes and more (NYC office buildings), floating on contained light, totems intoning cadences of windy stories spoken to the shivering back. Jokes. Jokes you don't laugh at since you don't know when. (Meditative punch-lines.) Squared lips mouthing them, saying something known but forgotten. Dead-pan. Elegant. Ancestor.
Von Huene's art is located at a point just between those turn-of-the-century fantasies of machines that come alive, and archetypal evocations that reach beyond time. It thus escapes both the topicality of modernism and the datedness of the recent past. There is no nostalgia in his beings who articulate their own existence almost didactically and "in tongues." They seem on their own, stylistically removed from now just enough to perform without either necessity or apology. They are perhaps even a little smug in their mystery. What they are not, that is, what is absent, is of no importance to them. It is what makes their magic so potent.

1967 – Pneumatic Rubber Tube Sound Sculpture – David Jacobs (American)

Born 1932 in Niagara Falls, New York. Studied in California, obtaining his M.A. at Los Angeles State College. Presently Acting Chairman, Fine Arts Department, Hofstra University, New York.
These photographs [in attached pdf] and pages from my sketchbooks arc presented more or less in chronological order and deal with inflating sound sculptures and sound performance/exhibitions I have made since 1967.
There arc two distinct and quite different groups of sound sculptures. The first group was presented variously under the titles "The Wah Chang Box Works Assyrian Air Fair," "Mothers Mechanical Wonderful Wah Wah," "Wonderful Wah Wah," etc., and consisted of sculptures which generated reed sounds and in some cases simple escaping air and motor sounds.
The second group dating from late in 1969 and still being added to is called "Wah Wah" (being the name of each piece as well as the group as well as the performance) and consists of sculptures generating excited columns of air. The more mysterious airy sounds of the Wah Wah seem to defy identification and placement hovering near your ear or in your head or just past you beckoning you to a place of privilege.
Sound is an integral part of my sculpture at this time, shaping space at least as effectively as any visual elements.
A commentary follows on pages 63-67 see pdf here.
