Cell phone transforms into music playing cube

Already cell phones are doing a lot of different tasks, becoming a lot of things to their owners, virtually transforming into still cameras, music players, small computers, and even camcorders.   But the KDDI AU Design Project in Japan has taken that ability to transform into the physical realm with a phone that becomes a music playing cube, complete with speakers and visual display. 

Box to Play, as it is called, is a concept phone.  There is no word yet as to it being produced commercially.
