Where do you go in minimalist design beyond the iPhone? For now it seems that flat slabs are the computer object design for the immediate future.
But what if the whole slab was a screen? That's a question answered by the "P-Per," a concept from the Chocolate Design Agency showing a phone that is wrapped in an e-Paper display, allowing it to pull off some pretty nifty transparency tricks with its camera. (There's nothing that would stop the iPhone or any other camera phone from doing this to a limited extent right now except for camera refresh rates and the depth of focus.)
