The May issue of "Radio-Electronics" describes several 3-D tv
and movie systems.  The best of them uses special glasses that are
shuttered electronically in synchronism with the fields of the
picture.  The frame rate has to be stepped up to avoid flicker,
but the effect is true stereo vision without color distortion
or orientation problems.  It works by showing alternating left
and right frames of a stereo image and shuttering the glasses
accordingly, so each eye sees only its correct image.
The problem is that it's not compatible with existing video
standards, so it probably won't hit the consumer market.

The system could work in a theatre if they could make the glasses
wireless and light enough for comfort, but they'd have to do
something about the 24-frame/s framing rate of the standard projector.
