1. Ply design phone
Ply’s name is taken from the design of multilayered plywood, and each layer has its own very distinct function, ranging from a photo printer to game controller to mini digital projector.
This is of course a concept only, but in this day and age does it seem out of reach? With all the amazing games available on Japanese handsets, the controller layer is a definite plus, though it would be even better to have a wireless version to use while using the built in projector!
