Dear all, here is some footage I dug up from just messing about with shapes. It's a fairly simple idea - two circles that I transformed /morphed according to random keypoints. I thought about it when we were at 52 as we mentioned motion-tracking- what if we could find a way of translating these changes to the movements of an individual/ group of people? I know there are programs that allow you to edit 'live'. This is only a sketch, and we could use different shapes, colours- anything u like really. Never mind the 'twitches', I wanted it glitchy at the time.
Also, sorry to ramble, but I found this diy : very simple idea but pretty, adds a sculptural element, and also fits into the analogue-digital theme:
256 wires suspended, projector projecting horizontally to correspond with them. Personally I think it would be too frustrating + fiddly - you have to register the pixels with each wire. Eek! Search 'wiremap' and theres loads of tutorials on how to make one, and the code is open-source! People are doing all sorts of things with the idea, including moving 3d objects - a bit like a hologram.
