Algo.Rhythm: computational thinking through tangible music device

I present the design of Algo.Rhythm, a tangible computational drum kit with programmable behaviors. By arranging and physically connecting a number of drum-bots, each of them records beat patterns from outside world or its precursor, replays the patterns in selectable ways, and passes the rhythm to its neighbors along the drum-bot's surface in 3D space. The construction of drum-bots and the delivery of the beat patterns provide users a unique opportunity to learn a set of computational concepts like sequential execution, iteration, or forking through composing music.
