RDS    2.1    Single Image Random Dot Stereogram genr.

Single-Image-Random-Dot Stereogram generator.  A random dot stereogram is
a picture that looks like snow on a TV.  By training your eye muscles to
behave in a certain way, a 3-D image will magically appear.  I do not know
the specific optical properties that cause this to work.  All I know is
that it does.
