Just playing with isosurfaces. I like 'em a lot!
This ring is built from 2 isosurfaces. One is a sphere minus cylinder, 2
planes and the holes. That forms the reflecting ring. The second
isosurface is the green stones. I used a similar technique as described
in Mike's absolutely great isosurface tutorials here:
http://www.econym.demon.co.uk/
I used photons and focal blur as you can see. Render time was 2h on an
AMD 2600+ @ 2100MHz.

This is another version of the ring without the slow focal blur. The
ring looks better IMO - the color is more reddish and there are less
stones. FB might make this a nice image - and a slow one to render :)
This took 4 minutes to render.

Because I wanted to play with them :) It is correct that these two
images could be rendered faster (depending the number of holes. More
holes means that isosurface is faster) and maybe described easier with
primitive shapes. I just wanted to try how to operate with isosurfaces.

This is the final render. 10'000'000 photons, 60 blur samples in focal
blur and 5x5 area light with adaptive 1. It took 3h to render this - of
which 2m 43s to shoot photons.
It is funny how the caustics on the checkered floor look almost like
reflections. The floor, however, is not reflective. I think this effect
could've been reduced by using less photons.
