A year ago, at MacWorld Expo SF, E-Machines was demonstrating an
experimental 3D monitor for the Mac II along these lines.  The glasses
were of polarizing plastic, and were similar to light sunglasses when
looking at anything but the screen.  The screen proper was behind an
LCD layer, which changed its polarization with each refresh.  The
screen was extra bright to get around the light loss through the
polarizer.

The video card alternated between two images according to one of the
color bits, although they were planning a version which had two image
buffers.

All in all, it was pretty impressive.
