WATCH THIS VIDEO WITH CHROMADEPTH GLASSES!
This little hybrid between Mickey Mouse and Steve Mann enables you to control and view stereoscopic animations that are animated in real-time.
It's an old View-Master viewer modified to have ChromaDepth lenses, some custom buttons, accelerometer, bluetooth radio and an Arduino to control it all.
The Arduino sends the sensor data and the button states wirelessly via bluetooth to my computer. The information is parsed in Max/MSP, which in turn sends the data as OSC packets to Animata. Animata then animates everything in real-time and handles the hiding/revealing of different layers.
