Royal College of Art graduate Miquel Mora has this neat project called "Flat Futures," exploring the potential uses of digital paper:
“The Flat Futures project is an exploration into digital paper,” explains Mora, who originally hails from Barcelona but now lives and works in Paris. “Through printed electronics we can create processors, displays, batteries on flat and flexible surfaces like paper. Objects will wear technology instead of carrying it inside, it will become their skin.”
This one above is the conceptual design of a paper alarm clock (how do you turn it off? Just scrunch it up!)
