We're not sure how a concept design for a chameleon phone that mimics the colour and texture of any surface can make it into shops in two years, but that is about ten years in mobile phone time.
Our favourite is the Fold-a-phone, by Hanna Sahlen -- a compact mobile for popping in a pocket, which unfolds into a giant smart phone when you want the screen acreage. It uses miura-ori origami folding, apparently, which means you can unfold it just by tugging on the corners.
But anyone can draw a cool phone on a piece of foldy paper -- it's another thing to build a working phone. So it's no wonder Fujitsu is still trotting out its concept phone from last year. Its screen and keyboard pull apart to be used separately, and can be stuck together in different configurations using magnets.
The F-circle, with its round screen and keyboard, is way too similar to the gorgeous, but useless, Nokia 3650.
