Next Big Thing – Rollerphone

Er, I don't know where to start
It's a phone. Or a concept for a phone. And a watch. Clever, innit?

I'll be the judge of that. Tell me more
The paper-thin, flexible, transparent screen rolls out from the watch strap and can then be operated like any other smartphone. It's even capable of playing music, video and games.

All from a strip of clear plastic?
Not quite. The watch strap has a battery-life display, as well as housing the microphone. The speaker's on the retracting end of the screen so it reaches up to your ear when the phone's fully extended. And did I mention that the watch shows the time by projecting it onto your wrist? Well, now I have.
