Japan's KDDI AU Design Project designed this innovative new phone dubbed the "Box to Play". The phone can transform from a normal-looking cellphone to a box with a graphic music interface.
The phone has the regular features of cell phones, like normal calling functionality, camera, mp3, check email, etc. What separates it from the rest is its awesome LED interface that displays as an equalizer when showing a caller ID or when music is on. It has an embedded turntable that lets you to scratch your selected music as it's playing.
It's still not on the market, but I will keep my eye open for this gem.
