Hi Florian, these are very nice, well done! Glad to see I wasn't the only
one mesmerized by these objects.
You've inspired me to have another look at these things, so I'll try and
come up with something interesting to post.
By the way, if anyone is interested in the code I used to generate my
version Florian referenced above, it's available here:

Cheers,
Sam (aka scam)

Here's two similar ones:

-But I like your texture and light setting better !

So... is that something like taking the reciprocol of a complex number?

Here's a good introduction in 2D:

Seems to indicate that the reciprocal of a complex number is indeed an
inversion with respect to the unit circle in the complex plane.

It's a "straight" version of the isosurface used in this image:
http://hof.povray.org/Isosurface-Cubic_Space_Division.html
That structure looks similar to the one in the image in this post:

Transparency, ior and radiosity -compilation is also pretty good one ;).
