I tried a few of them on the alternate specular node, but didn't like what they were doing . I guess I could go back and spend a day just playing with the nodes and see what I can come up with. I don't have BB's knowledge of this (something tells me he's forgotten more than I will ever know), but it wouldn't hurt to experiment.

If I had a nickle for ever time a woman told me to get lost, I could buy Manhattan.
