MP3 Cube Controlled by Motion

Doing away completely with buttons and knobs, this cube-shaped MP3 player is completely motion-controlled. The music begins upon insertion of an SD card and stops when the player is laid flat on its face. Tilt it to the left or right to adjust volume, and tap either bottom corner against a surface to change tracks. Naturally, there’s a built-in acceleration sensor powering all of this. It’s just a concept device, so there’s little chance of it escaping the Japanese engineer’s lab and reaching the commercial masses, but it’s only a matter of time before another manufacturer apes the idea.
