1. buy some photo resistors at radioshaq.
2. cut open your guitar cords and solder resistor to ground wire.
3. gather as many guitar amps as you can and place them all over a room.
4. send sounds to all of them.
5. turn out the lights. all of the sound should stop.
6. as you shine a flashlight on each photoresistor, the sound should escape the amp that it corresponds to. Brighter light will produce louder tones.
7. compose pieces based one the movement of the light. compose using geometry rather than normal notation.
variation: get a strand of christmas-tree-lights for each amp (the kind that blink). attach one light from each strand directly to a photoresistor and drape that strand over the corresponding amp. plug all the lights in and enjoy the random composition that the dimmers produce together.
