Just awesome! How long did it take?

See you in Khyberspace!

Indeed ;) Although now I think I'll have to try whether the
intersection of a sphere with a sponge makes a nice ornament.

Thanks! Unfortunately I couldn't figure out a good way
to show a 3d division so this only repeats in one dimension.
Probably the menger sponge can be generalized to something
where the holes take up a larger ratio for better seeing
through but not trivially as it then no longer decomposes
into smaller subcubes that are otherwise identical.

Yes the color scheme is a bit dull, and only after rendering
it occured to me that it would have been enough to render the
left part as it's perfectly symmetrical ;)

Thank you! Render time was a bit over an hour on a high end
machine for 800x600 AA 0.1 with "Radiosity_Normal". This was
actually much faster than using multiple light sources, in
my first try I didn't even live to see the first block of
pixels rendered to completion. Guess the calculation of
shadows is a bit annoying here ;)

Nah. A traditional D&D gelatinous cube. :-)

High end machine... do you mean something like an AMD Opteron "Istanbul" 
dodeca-core with 16 GiB RAM? Perhaps even liquid nitrogen cooled? With 
my single-core Athlon 64 3500+ with 1.5 GiB I really should crawl back 
under the stone...

See you in Khyberspace!

I just meant fairly high end as in an i7 with 6 physical
cores / 12 threads. Actually I stopped following developments
after purchasing it a year ago, it may already be much less
high end than I'd like to think ;)

Looks like a rudimentary Borg ship.
