You know I was making all that up, right? Seriously, this one *is* made
from an isosurface, and I've included the source to prove it.

To be honest I had to look at the Isosurface manual to find out, what a
strophoid is. Not bad, as this one is a bit differed reflective sphere over
checkered floor. Just reports 1 object, 0 infinitives in the stats, doesn't
it?

Anyone willing to beat that?
