Muharrem Yildirim, David Tinapple

Animation is projected onto a freely spinning disc where viewers can spin the disc by hand. Computer can detect exact rotation, position and velocity of the spinning disc using an optical rotary encoder mounted behind it. An interactive physics simulation is projected onto the front of the disc which responds to the real-time position and speed of the disc. Synthesized sound is triggered according to real-time physical collision in the animation.

The resulting system is quite simple at first glance. But upon interacting with it, and spinning the wheel, it comes to life. The physics feel right, and match the motion of the wheel. Gravity seems natural and honest. And the sounds seem to give the basic shapes a sense of solidity and resonance. The piece tends to attract people to it and can become hypnotic.

Developed with Processing, Max/MSP, Logic.
