Fujitsu and Japanese telecoms company, NTT DoCoMo, have released a new concept mobile phone which literally falls to pieces.

The "Separeeto Keitai" may looks like a normal flip phone, but you can actually pull the keypad from the screen thanks to a magnetic hinge.

Once the two parts are separated, in-built sensors will pick up on how they are orientated and change the interface to match this.

The touchscreen section can serve as a virtual keyboard, numeric keypad, or even a game controller.

The idea - you can make calls with one half whilst using the other to pen emails, and all the while the two will communicate using Bluetooth.

Clever eh?
