Get ready to be impressed because this is the first ever real working prototype of an electronic reader based on a flexible e-paper. The READUS is essentially a 5-inch screen that runs at 320×240 pixels that rolls up just like a scroll. The screen is by E-Ink Corporation, and basically uses power to change the state. The display uses very little power and is easy to read at night or even bright daylight. When you’re done reading, just roll it up.
