"Single Image Stereograms (SIS) are two-dimensional images that
seem to be three-dimensional; these 3-d images appear to 'pop up'
(or 'pop down') out of the printed paper. The amount of training
the typical human nervous system requires to see such images seems
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.
"The history of how I got interested in stereograms is at the
end (see section 6) of this document..."
