The latest competitor for MP3 player domination comes out of Japan (where else?), where an engineer friend of Engadget, living in the town of Ageo, has built a motion controlled device that plays tunes from an SD card.
Housed in a set of speakers (switching from stereo to mono when the satellite is unplugged), the very DIY device has an accelerometer-based interface: you can skip ahead, skip back, change albums, pause, loop, turn down or crank up the sound by tilting, tapping, or setting the thing down.
Check the video and if you want to build your own, there’s a parts list, schematics and firmware page.
