Actually, I think that's supposed to be SIRDS, an acronym for Single-Image
Random-Dot Stereogram. (You leave the final S even in the singular form,
since it's part of the acronym.)
A Google search for "surd" brought up a few rather different definitions,
which I leave as an exercise for the sufficiently curious... :)

While researching 3D imaging and stereoscopy a few months ago, I had
stumbled on some examples of 3D ASCII art, but these were either stereo
pairs or of the stereogram variety (like random-dot stereograms, but with
repeating patterns of ASCII characters). I hadn't come across any ASCII art
anaglyphs yet. Do you happen to remember where you had found that?
