Outstanding ... I'll keep an eye on revision control. I'm anxious to get 
it a test drive. Since, it would seem, that my sea shell attempt at 
using iridescence is what inspired you to dig into this, I have a 
question about the aoi pattern that was mentioned as an alternative ... 
you wouldn't expect it (aoi) to respond to other pattern modifiers 
correct, as it doesn't appear to. However when I read the doc passage, 
"It gives a value proportional to the angle between the ray and the 
surface" it makes me think that's correct behavior. If this is true 
enough, perhaps I should make a slight addition to that passage to clarify.
