Gnarly!

After admiring BeesKnees67's beautiful fractal abstracts on DeviantArt last night, I felt like making something brownish and abstract myself. The formula I used was Very Advanced Gnarl and the colouring algorithms are too many to mention! ;) 
This fractal has 12 layers and it took ages before I was happy with it. I like it a lot and I think it's a bit different from what I normally do. We'll see if I post it on DeviantArt or not, I haven't decided yet.
