That guy with the funny hat who sometimes blogs for us built a touch-to-play spoon organ and showed it off at Make Tokyo 06 this weekend:
The user can play musical tunes simply by touching a row of spoons sitting on a table, with a fork added in for good measure. A microcontroller is used to detect changes in capacitance caused by a finger pressing against the metal, which are then sent to a computer using the MIDI protocol.
