appropriate eyeball. There are two common ways of doing this:

- Use different colors for the two views with color filters in from of
each eye to separate the views. This is what were often used for
the really bad (content wise) sci-fi movies of the '50s.
- Display alternate views on the same monitor screen but use LCD shutter
glasses to allow each eye to only see the appropriate view. This requires
increasing the refresh rate to avoid unacceptable flicker.
The first approach can be used with any TV and a pair of monochrome
video cameras. Of course, true color cannot be used since pure colored
images are needed to separate the stereo views.
Alternating views with synchronized LCD glasses is a possibility but
on a standard TV, the resulting refresh rate would be 30 Hz with a 50%
duty cycle which is likely to be useful only as a short experiment - else
your viewers will likely develop splitting headaches.
