3-D. CREATE AN EXCITING FILM-GOING EXPERIENCE.

It's called stereoscopic 3-D.

In a traditional film-based 3-D system, two projectors team up: One continuously displays a reel for the left eye, the other a reel for the right. But in newer, digital 3-D systems, one projector simply runs twice as fast -- 96 frames per second -- displaying alternate views, left, right, left, right, one after the other. Directed by an infrared "command" pulse that comes from the projector, the moviegoer wears a pair of LCD glasses which "shutter" in synch to transmit or block light: the left lens opens for its image, while the right lens is turned off. Then, the right eye sees its frame, and the left lens is turned off.

The prototype glasses will initially cost theaters about $25 to $30 per pair, and can be cleaned in a dishwasher, according to IN-THREE CEO Michael Kaye.
