StereoGraphics (415 459-4500) sells a thing called (I think)
a Z-Screen.  It goes over the monitor and circularly polarizes
every other frame.  The viewer wears passive polarized glasses
that look like sunglasses.  This is the most economic solution
for when you need to show a stereo image to many simultaneous
viewers.

The Z-Screen (or something like it) can be used with a projection
television to create really big stereo images.
