The first thing you notice about the Double phone are the solar cells across its facade. The second thing you notice is the 360º hinge. Pretty cool looking concept with the added benefit of never running out of power as long as the sun is up. Spec wise, the 3.2 inch LCD screen, touch interface and transparent panel for notifications is more than enough to keep up with the big boys in the market.
The Double is a Red Dot Concept Design winning entry.
