Light-emitting wallpaper?

A while back I mentioned LED lights in a blog - well by 2012 The Carbon Trust say we could be using light-emitting wallpaper. A chemical coating on the walls will illuminate all parts of the room with an even glow, which mimics sunlight and avoids the shadows and glare of conventional bulbs. An electrical current will stimulate the chemicals to produce light, but the voltage will be very low and the walls safe to touch. Dimmer switches will control brightness, as with traditional lighting. See more here.
