This concept phone from Japan’s KDDI AU Design Project looks quite interesting, though it most likely will never make it to the general public. The Box To Play, as it’s called, has a camera and the usual mobile phone functions, but it’s very much inclined towards the musical side of things. The phone itself can fold out to form a box shape, which will have a graphic equalizer displayed on the sides, and users will also be able to “scratch” music on it, to fulfill all their DJ dreams.
