Something reminded me of this graphic that I'd seen about 20 years ago when
I was attending an ACM symposium. When I got back to my office, I coded it
up in Fortran and printed it on a Calcomp plotter. Yeah, shows my age, but
isn't it still an amazing eye trick? I tried using various textures and
lighting schemes with POV, but it seems to work best as a simple B/W image
and orthographic perspective. Anyone want a wallpaper version?
