Cubed MP3 Player Rolls for Control

This is a gadget built from scratch from a guy named ChaN. It uses a three-axis accelerometer to help control playback, next track, previous track, volume control and pause/stop. It loads up Mp3s via SD card.

The above link shows how this guy made this thing. He should just go build them and sell them online in mass production. Judging purely from the video the sound quality is pretty damn good. [Gizmodo]
