This is bananas. Canadian researchers are showing off a smart phone called the PaperPhone that is about as thick as a piece of paper and feels like a piece of plastic. It’s operated by bending or folding different parts.

From the BBC:

“This computer looks, feels and operates like a small sheet of interactive paper,” said Dr Vertegaal in a statement. “You interact with it by bending it into a cell phone, flipping the corner to turn pages, or writing on it with a pen.”
The millimetres thick prototype is built from the same e-ink technology found in Amazon’s Kindle e-book reader and this is bonded to flex sensors and a touchscreen that interprets drawings and text written on it.

It’s going to be shown off at a conference May 10th in Vancouver. The same team is also working on a tablet version.
