Motion sensors attached to various parts of the body read your movements and a central unit changes them into sound. Wave a finger slowly and a lone violin plays. Stomp around, and the timpani booms in time with your footfalls. Strum your fingers on a desk for a drumroll. And conjugal overtures, anyone?
One setting would use simple tones of one instrument for each sensor. Another would assign synchronized single-instrument tracks from a prerecorded piece to each sensor - for those who want to conduct an actual orchestra from the comfort of their own armchair. The faster you move, the louder the corresponding track.

Also projects a solarized image of the participants on the screen in front of the participants.-- phoenix, Nov 06 2003 Seems extremely similar to "Branch Director" posted just yesterday, you're just using a different source of input.-- krelnik, Nov 06 2003 Actually, it verges closer on that old HB favorite, the theremin.-- DrCurry, Nov 06 2003 Thought of this on the way home from school the other day, I hadn't seen that branch idea.-- Qinopio, Nov 06 2003 random, halfbakery
