Doki Doki is a highly tactile wooden digital hand-drum with five active surfaces and a built-in accelerometer. While the product is easy and intuitive enough for a kid to instantly understand, a professional musician could in detail program samples, synthesizers, loops and effects or use the interface as a MIDI controller for studio production as well as live performances including real-time generated synchronized visuals.

Oh, did we mention it is based on open source hardware and software?
