I thought I had a brilliant idea on to solve the bulkiness of today's full keypad phone. Well, it turns out to be just some what 'interesting'. But I decided to post on here anyway.
The idea is simple, the special geometry combined with a offset hinge to achieve the rotation as shown. The QWERTY keys align with the number keys in the front to form a 'real' full keyboard layout. Interesting, isn't it?
