I'm sure this is far away from what actual nubby silk looks like, but it's kind of nubby and kind of silky, and I like it.

What I really need is a better understanding of how the fBm node works so that I can do per-thread variations in thickness and coloration in a random but controlled way. So, I guess I'll work on that now...
