E-paper shows images even when unplugged

Fujitsu's e-paper is an electronic surface that uses liquid-crystal technology to display a still image. What makes it remarkable is that once that image is loaded, it stays there without consuming any energy. Shown above is a prototype of the paper, which is rather small, but Fujitsu claims to have sheets as big as a normal piece of paper in development. The technology will probably first be used for store price tags, train schedules, and boring stuff like that, but it certainly has the potential to be used in more exciting products, like digital picture frames. Although the tech sounds remarkably similar to E Ink, used in Sony's upcoming Reader, the fact that this picture is in color (the Reader's screen is black and white) ticks up the excitement a few notches.
