I bet with some wires, a row of spring-like contacts, and a few other things, you could make an electric one of these.
Not sure if I'd simply hook it up to some tone circuits, or if I'd get fancy, and rig it up with some relays and solenoids. Then it could play all sorts of instruments. Maybe something that fits onto a piano keyboard. Or strikes xylo keys. Or hits drums. All sorts of possibilities. :D
