Hi all,

I originally made this image over a year ago, however at that time the
version of POV-Ray I was using had a bug which made the sphere_sweep
objects very glitchy. It remained that way until Florian pointed out that
the bug wasn't present in a previous version (3.5) and so all of a sudden I
was back in business.

Anyway here is the image. It is an inversion of a 3D truchet tiling, where
instead of the mesh it was originally made with I now have nice smooth
sphere sweeps (which look much better, and are ~ an order of magnitude
faster to render). Render time was about 2 hours.

While I have your attention, does any one have any alternate
texture/lighting ideas? At the moment I just have an area light and a red
point source inside the object, and a very basic texture.
