to vary from person to person; it seems to help if you are old and
myopic! This tutorial is not about that however; it is about
creating the images that will invoke the 3-d image in the eye a
trained beholder. I will explain how I created such a stereogram of
(what is to me) a beautiful mathematical entity called 'Borromean
Rings.' The techniques described are sufficiently general that
readers should be able to create their own images. In particular,
the reader may want to construct a depth map for something else
like a trefoil knot or a fish.
