Shit happens! :^) For some damn reason I have mine right by my computer. 
Strange in a sense. ;^)

Now, think of viewing a "special" stereogram that takes the "special" 
depth map's red and blue color channels into account. I think that 
viewing the stereogram/anaglyph hybrid thing would simply have to 
involve the observer doing the eye thing _while_ wearing the glasses. 
Afaict, it should be able to work. I think so.
