Here’s an interesting concept from designer Andy Kurovets, called the Bend mobile. The idea is that it is compact, with a second screen and a camera popping out from inside. The idea is not without precedence. All kinds of cameras used to fold out and become larger, accordion style.
Basically, it grows to nearly double it’s original size, which should appeal to those who feel their current cameras are inadequate. Treating the device like a swiss army knife is a great way to pack lots of features into a mobile device and it should probably be taken seriously by manufacturers. The whole thing is also curved, for easy sliding in and out of your pants pocket.
