Sharp Corp. has developed a liquid-crystal display that shows totally different images to people viewing the screen from the left and the right.
One catch is that the images overlap if viewers stand right in front of the screen. Moving a few inches to the left or right may be necessary for a clear view.
Another drawback is that users will have to work out a way to listen to the sounds coming from the different channels. One solution is for one viewer to use earphones.
DH just sent me this link. Said -- "You and your friends might find this interesting."
Sounds like those little pictures that appear to "move" when you rock them back and forth in your hand because if the clear vertical plastic ridges. Sounds like the same concept, but completely different.
Thanks, honey! Um.... when can we get one??
