This took a surprisingly long time to render: 58 minutes for the photon mapping
pass, 2 minutes for the first radiosity pass, and 23 hours for the final pass,
on an Intel i7 with 8 cores.  The first two passes were rendered at 1/4 scale
with no anti-aliasing, area light, blurred reflection, or camera DOF.

Blurred reflection is courtesy of module RC3Metal from the Object Collection.
CLipka's blurred reflection will surely be faster than mine, but at least mine
is available today.

Source code for the basic shape and an explanation of the geometry are posted to
povray.binaries.scene-files.

Good job, Ricky; it looks nice! Needs a more interesting environment, though ;)

My version took longer to render than I thought it would, too, even though it
was built out of clipped & unioned geometry, and didn't use many standard CSG
operations.

You might gain a few PPS by specifying your own bounded_by objects (POV-Ray
doesn't always produce the most efficient bounding boxes on its own), and also
by making the base object a slice of the final object. That is, the base object
would be a single "lobe" that would then be copied and rotated about the center.
