"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.
