Feedbackophone

This would be a spin-able chamber like a gerbil wheel encased in transparent plexiglass with a crank on the outside, like the contraption they use to pick numbered ping pong balls in powerball lottery contests, filled with a variable amount of size-optimized foam balls, some containing wireless microphones and some containing wireless speakers. The resulting feedback would be compressed and otherwise optimized so that it is dynamic and aesthetically pleasing. The speed, number of balls, ratio of mics to speakers, post processing, size of the chamber and other variables would have to be experimented with. Maybe this would work better if all the variables were computer controlled. I guess the whole thing could probably be represented by a what do you call it javascript simulator.
