EggBeater uses the intuitive power of rhythm to let anyone control the playback of music. Shaking this small, wireless device in regular patterns can automatically adjust the tempo and timing of loops. Just start playing the EggBeater just as you would a traditional shaker, and listen as the song slows down as you slow down, or speed up as you do!

EggBeater uses an accelerometer coupled with an XBee radio to send your movements to PureData, where they detect your downbeats and rhythmic tempo. The software can then control playback within PureData or send OSC or MIDI messages to other platforms.
