Very good and useful but not what I want (for this thread anyway.
Really awesome as far as helping me understand OSL!). I don't want a
OSL node because the average artist will run screaming from anything
to do with programming.
The other problem is that it will not render on my nice new FAST
graphics card. OSL is currently CPU only.
