Solar Paper
Solar paper is an actual childs toy. You take the solar paper and put different designs on it and then it illuminates areas in creative ways.
On the horizon is electronic solar paper that is embedded with tiny microchips. For example, you might have some electronic paper that is actually able to download online books or to accept word processing tasks. The thing is that the paper will have to be very thin and the goal is to emulate traditional paper so well that people will not prefer print to electronic media.
