Bit quiet on p.b.i. at the moment, so here's some shiny things.

These are the Platonic, Archimedean and Catalan solids. How many can you name
without resorting to wikipedia or wolfram? :-)

The photon mapping works quite well with those objects.

Sweet! What's the max_trace_level?

Beautifully. Although with count=7e7 and 31 targets, the photon gathering stage
took well over an hour!

I left it at the default. I'm sure raising it would make some sort of
difference, but it looked fine so I didn't worry.

Hehe. Before now, I could have named the platonics and probably half the
archimedeans (although I wouldn't have known they were archimedeans). I still
can't remember any of the catalans. They're all triakis-this and
rhombic-that... :)

Funny, I thought of it as a floor... it's an isosurface. If you look closely,
you can see relief detail illuminated purely by the caustics.

  I think a simple plane with a proper normal block would have resulted
in a practically identical image but much faster.
