The piezoelectric effect is an interesting phenomena. Capable of turning vibrations into electric signals, it's at the heart of the Mogees project from Bruno Zamborlin and Norbert Schnell. Here, a contact microphone is connected to a system that processes sound from unique gestures and then triggers the appropriate instrument in its database -- thereby turning virtually any surface into an experimental jam band. Different gestures may be added to Mogees, which can also recognize the difference between fingers and objects such as coins. The project isn't commercially available, but if you're unfamiliar with the magic of contact microphones, we think the video after the break will be a rather fascinating introduction. Hell, with a similar setup, anyone could be a budding musician. Just don't let it all go to your head if you make the big time.
