It seems like all that is needed is an electrically controllable polarizer in front of the screen, say a fast liquid crystal panel. Alternate images would be visible to each eye if you wore polarized glasses. I've seen color stereo slides using a projector which projected two images of different polarizations and a special screen which did not disturb the polarization. It was pretty impressive; sometimes everyone in the lecture hall just about went cross-eyed trying to look at something that was six inches from their noses. I saw slides of cave passages and it was the closest thing to being there I've ever seen. It seems like this would be great for a big color projection tv. There is still the inconvenience of having to wear polarized glasses, but it seems like a small price to pay. Ditto for the extra bandwidth required to send twice as many images for the same picture quality. Maybe it will have to wait until after the high resolution tv standard is developed and in place.
