Ordinary TV sets deliver 500 lines of resolution. Most high-definition screens reach 1,050. The HD3D hits 1,280 lines and counting, meaning better picture quality than that of any TV available today, all in a convincing impression of the third dimension. And here's the seriously mind-bending part about the new screen, which Deep Light plans to introduce at the Consumer Electronics Show in Las Vegas in January: One screen can show different programs to different viewers at the same time.

Imagine what that could do to the living room. A child sprawls on the floor, happily splattering the virtual walls of Quake 3-D, while one parent sits on the couch watching the news and the other talks with friends in a virtual chat room - all on the same TV, all at the same time, and all in three dimensions. Lean a few feet to the right, and the latest report from the floor of the stock exchange becomes a live 3-D chat with the couple who came over to dinner the other night; lean the other way, and Junior is blasting a zombie.
