Just for fun, playing with the AOI pattern today; I was going for a
styro-ball-and-stick, circular double-helix (bacterial DNA) sort of model.

As you might expect, I had to use pretty high radiosity settings to avoid ugly
blotches where the balls touch.

Cheers,
Rob

Looks good, Rob!

The AOI might need a non-linear falloff. I usually do something like this:

 pigment_pattern{
  aoi
  color_map{
   [.5 rgb 1]
   [1 rgb 0]
  }
  poly_wave 2
  color_map{
   ...
  }
 }

It's probably a matter of preference, though.
