Apologies if this offends anyone who did the earlier 'raytracing desktop'
images. Not that reflective spheres over checkered planes are that original
in the first place =)
Anyway, this is my version... I placed 16000 spheres in about 13 minutes
using a faster algorithm that I developed (still O(n^2) though... sigh). It
took about three days to render thanks to focal blur + area light + media
(even using a spot-area-light for the closeup area and a regular light for
the rest). I used Photoshop to slightly clean up the focal blur artifacts
(a maximum of a 2 pixel gaussian blur in the background, one pixel in the
middle ground, nothing in the focused area).
The checker pattern uses a very nice function I made that is like the
checker pattern, but has even gradients into the center of the squares, so I
was able to easily make grooves between the "tiles".
Comments?

BTW, the original render was 1400x1050 (which explains the long render time)
if anyone's interested.

This is more along the lines of what I was getting, albeit not on a
tilt. I just couldn't make the checkers look good whenever I tried to
emulate the previous method.
I like it Slime. It's almost grim enough. ;)

I love it Slime! A traditional raytracing desktop with traditional render
times! Ahh, the memories of sitting in front of my Amiga 2000 waiting as its
7.16MHz 68000 chip chokes on a reflective torus in Imagine ;)

This is a beautiful render, and the tiles are very clever. The in-focus ball
so close to the center of the image destroys some of the interest for me,
however.

Thanks, I'll use this one. Hmm there's an easier way to do that checkered
thing you're talking about, I just need to think for a minute.
