Chris Williams has put together a unique concept design for an MP3 player which is controlled by twisting and sliding the edge of the player. The Musipen (music and pen, get it?) moves away from current players and offers up an original but still highly usable interface. Although not nearly as original and usable as the MP3 player I designed. It's made out of fruit and you control it with your mind. I lost the prototype, but trust me, it was awesome.
