In Art and Sound design my group was composed of Matt, Cheston, and myself (Steven).
Initially our project began as "Invisible Drums." The general Idea was to create a drum set with nothing in sight except for maybe a few spotlights. We planned to do this using photo sensors or infrared sensors.
We had one logochip rigged with photo sensors just to see if they would be sensitive enough. We had a small flashlight that we waved over the photocells. Low and behold... they worked great!
However, somewhere between the Drums and the waving flashlight, we concocted the idea of “Digital Wind Chimes.”
We planned to build an arch from rebar. From that we would hang flashlights aimed at photocells along the walls and floor. As people walked through, their shadows would trigger various sounds as the photocells were tripped.
For a few conceptual images of the arch go to: www.angelfire.com/planet/gu3d/chimes (sorry about the watermark).
