The Eyes of the Poet

One of the films that most impressed me when I was a young aspiring filmmaker was undoubtedly Un Chien Andalou and its memorable eye-slicing scene was particularly impressive to me. Whenn I was seven years old I had had my left eye cut by a piece of glass thrown to me by a childhood friend which required seven stitches right next to the pupil. This event changed my life forever and I believe in a positive way as I look back (pun not intended).

First of all the impact on my psyche was considerable. Since all eye operations occur with your eyes wide open, it is inevitable to see what it is being done, even if you are under total anesthesia, like I was.

The surgeon did not believed me at first when I told him that I had seen all the operation until I started describing in detail what I saw. This images were burned in my mind in a very permanent way, and for many years, until my young adult age the sequence of events (the operation itself) would run unannounced like a silent film of yore. When this happened I had to immediately stop whatever I was doing and change to something opposite of that, for example if I was alone I would try to find people, the more the better, like a crowd. But when I was in a crowd or a party and the film started to run I had to immediately find a place where I could be alone. Only then would the operation fade and let me go on with my life. Then one day this vanished never to come back again.

My sight never recovered and so I would see very clearly with my right eye and completely out of focus with my left, since the stitches distorted the pupil. This became extremely useful when I was a cameraman, since I did not have to close my left eye when shooting like everyone does. The main reason you would close the eye that is not looking through the viewfinder is to prevent confusion as to which image you are supposed to be seeing. The view from the lens would never be the same as the naked eye and therefore the mix of both images would be very disturbing to some people. However, my two vies were so radically different that I was able to use the out of focus image to my advantage. The left eye could (barely) see that which was outside the frame and therefore I would be aware of something that was just going to happen around and could pan to frame it or to avoid it.

Back to the creatures eyes and the relationship with all of this. I, and apparently Lorena, my wife, as well have lived and still do in a close relationship with the dream world, which as you know is not always your "dream world" since nightmares and surreal events can be pretty scary. It si just that we have both decided to turn these experiences into the stuff of art, bringing this parallel universe into the "real" world for other to see.

Re Cycle beneath the wheel

The Creator stage in progress

People, myself included, talk about reducing our "carbon footprint", a term about to disappear from overexposure the same way any word repeated over and over loses its meaning as it is replaced by noise. At the same time we blog about it, consuming terawatts of carbon producing power exacerbated by the inefficiency of bloated operating systems, the apparently innocuous white screen of Google, by the energy consumed by the avatars in virtual worlds that need to be kept virtually alive by the server nodes and the computers around the world that hum incessantly without any hope of ever being silent.

Our self-made society has plugged a cannula into our collective vein, to transfuse itself into the mind of the machine, which like a life support system we cannot disconnect, or at least we think we can't, that is, until the plug is pulled by the system itself when no longer needs any more information, other than the one it itself generates.

WW II direct interhuman syringe.

That is the story of The Creator with which we are trying to portray, using puppetry as a transference medium, the stark reminder of our self-dependency. Who or what controls who or what?

On to the practicum.

Since I detest plastic and the many woes and sickness that has come as a result of its indiscriminate use, I try to target it as a primary candidate for recycling, which is just a palliative approach to the real problem. In any case, I took the vacuformed package of the "energy saving" bulbs that we use nowadays, and just as I was about to send it into its recyling path, I noticed a form which reminded me of ancient alchemical apparatuses which I needed to create for the robotic-marionette stage. So here is the process:






The background, built over the "hardware cloth" is semi-translucent, with the most translucent parts being the "genetic" containers which will transmute common information into a panacea.

A digital projector, fed with data generated imagery will fill up the vessels as well as create the fluid digital environment where the Creator lives.


Here is the very first test as seen from behind, where I am trying unsuccessfully to line up, scale and correct the angle distortion. As you can see I missed the mark by a few centimeters. I am now in the process of positioning the elements as close as I can to the target, given the limitations of inexact everything.

What was I thinking...

Just to finish the pulley rant, I created a template to drill the round wood pieces that I bought (99c/bag) at the local craft store. They seemed perfectly round in the bag...



Much to my surprise (am I new? or what!) they were far from round, I found out when I tried to fit them in my template. To make it short, I sanded them enough to fit, drilled and glued them together. As I was venting my frustration for not finding proper pulleys, my wife who works next to me in the studio, asked why I did not use the spools that she uses for her beading or the ones that I use for stringing (fish line) the marionette.

DUH!

I must be very tired, been sleeping 4 hours max for months now. why didn't I think of the spools which were in front of me? So, here, I have a steady supply of the perfect size/weight spools.


I only needed to create bushings to adapt to the servos, real servos that is, not the modified ones by Vex which of course have a "proprietary" square shaft that only fits their kit stuff, I still cannot get over their lack of foresight and integration with the rest of the world. So much for Open Anything! Dean Kamen, you know much better than that!

I created the bushings with an aluminum rod that happened to have the right diameter.
I drilled the shaft hole to attach the Hi-Tech servos I will probably use, notched them to hold the adhesive better and epoxied them to the spools.

Stage Hands

Assembling the motion section and adjusting the elements so they fit.

I love that time when you have to finally begin working on the stage for a play. It means the performance is imminent (unless the producer pulls out!). It is also time to listen carefully to the director, designer, performers, lighting and sound people and stage hands and riggers to make sure all points of view are represented and taken into consideration. (if only it was like that in real life...)

Since the hole pattern in the VeX system is not really well designed (unless someone proves the contrary) I had to notch and cut lots of pieces so that they overlapped correctly in the configuration I needed. As I said before, I think the engineer/s who designed the system probably did it with a preset number of projects in their mind.

I would go back to the drawing board. It seems strange to me that in this age of CAD and relational tools, they could not test at least a few thousand combinations and optimize the design for that. So anyway, the metal is soft enough that it doesn't take that long to adjust.

The Vex control modules, servos and power supply.

Except for Lorena, who is the human performer, choreographer and costume designer for the project and who makes sure her needs and demands are met:-), the rest of the crew is me with occasional help from my friends, like Philip who is working on a Flash interface to control the microprocessors and sensors. I have my doubts about the speed of the image processing functions in the new Flash, but it is worth a try.

For now I am using VeX to build the stage support and to prototype the motion and control system. Ideally I would like to use a faster microprocessor, perhaps Propeller by Parallax which is a multi processor where each one of the 8 processors can operate simultaneously giving you the ability to respond in real time to performer actions, which is what I need to do.

Easier said than done, since programming is not my forte, but my friend Philip, who is in his final year in Architecture, loves coding and we have done great work together. I need to complete the prototype so that we can start programming and optimizing. Everything simpler, easier, faster. Like Ars Electronica 2006 theme said, SIMPLICITY - the art of complexity.

The Creator's new feet

I am also getting so much more familiar with the marionette I've created, since while you are whittling away at blocks of wood and dealing with joints, balance and many other issues, it is difficult to meet the creature on its own terms. Although it is not awake yet I can already see a bit of its character. This is an experience which every puppeteer, or for that matter any artist goes through as it transitions from production to contemplation or analysis and finally to understanding or appreciation.

This process is not so familiar to the engineering folks, since for them, in the majority of cases, everything must be defined or though in toto in advance and there is usually little room for improvisation

The Beauty of the Fall

The beauty of the Püterschein system is, as you can see in this picture, that the puppet assumes very natural positions with no human intervention. I just cut the string that held it up and it fell on its knees just like that! A true predecessor of inverse kinematics!.


It seems like it is praying for arms, looking intently at the cut rods that will give it the expressiveness it needs.


I cut an old broom stick to use for the arms, thinking that it was pine and it would save me some time if it already had a round shape. Ha! I don't know what kind of wood it is, but it was hard as oak and I have gone through a whole set of carbon steel blades just cutting it down to shape. It has taken me three full days to get them ready for testing! So much for saving time...





You can see the Creator now just standing naturally, again with only spine support. I did not pose it, other than bringing it down to contact a surface. Can't wait to have the entire body functional. In case you are wondering the "feet" will be (at least that is the plan) two slim inverted cones. We'll see how it behaves. As for hands it will have none in this iteration, since it will be all dressed up and have very long sleeves like the human performer in an earlier post:
you can see it here and in the original design so you get the idea.


This is a detail of the hip and waist rigging that holds and constrains those parts as the marionette flexes and moves.



After three days, a few cuts and sore muscles overall, the arms are close to ready. I've tested them and they move gracefully and have the needed range. Under the torso you can see the channel I gouged out to make room for a couple of screw eyes to pass the string that connects it to the waist and hip.

Next task: the HEAD! this will be interesting since it will have a wooden core or "skull" and it will wear a "self animated" mask, a fancy way of saying it will have some springs to react to any movement of the head. If I have time, which I doubt, I would like to put a micro-servo on the latex mask so that it can have a range of expressions in addition to the eyes. Lorena, who designed the original creature does not like the idea. Perhaps she is right. The simplicity of the spring solution, which we have demonstrated on performance gives such a varied range of expression to the Creator's face that adding more might be less. So there!
