BeetBox uses real beets to make music

BeetBox is a simple instrument that allows users to play drum beats by touching actual beets. It is powered by a Raspberry Pi with a capacitive touch sensor and an audio amplifier in a handmade wooden enclosure.
Here's how it works:
    Inside the cabinet is a Raspberry Pi Model B computer hooked up to an MPR121 capacitive touch sensor. A Python script detects any touches on the beets, and plays drum samples using the pygame gaming module system. The sounds produced are fed to an LM386-based amp and on to a speaker located behind the holes in the wood.
