Researchers create flat magic window with liquid crystals
Researchers have used liquid crystals to create a flat magic window -- a transparent device that produces a hidden image when light shines on it. The process for creating transparent liquid crystal magic windows can produce any desired image. The process can also be used to create magic mirrors that reflect, rather than transmit, light to create an image. The technology represents a new twist on a very old light trick, originating thousands of years ago in China and Japan.
