Thanks, RobynsVeil... I searched on Turbulence Node at that RDNA forum, but didn't come up with much that looks relevant.

But brick article at castleposer is pretty neat... not sure what it means for my implementation, but it's neat.

I do suspect that much of the problem I had was in the map... in order to get the wrinkles strong enough, the skin was too rough. Not enough contrast, I think. Am still experimenting.
