HOW TO - Build a Laserharp

"A laser harp is basically a big frame resembling a real harp. There are no strings. Instead, beams of laser light are projected from the bottom of the harp. These beams strike light sensors at the top of the frame. When something (a hand, foot, etc.) blocks the beam, a note is triggered on a synthesizer or some type of tone generator. Theoretically the harp could control anything but I'm interested in its musical possibilities." Here's how to make one! [via] Link.

From the article: "The electronics only detect the presence or absence of light so a PC was used as the brain/synthesizer when it was demonstrated."

Not sure how much music you can make with 12 binary signals, but the project itself is very cool.
