I had been working on some Christmas baubles and had been cutting out circles from patterns I had made.I was left with the outer corners of the original square pattern. This pattern has been created from those four corners.

I suppose this illustrates the point that brushes like these smoke patterns are not limited to smoke effects as can be seen on the lettering, but can be the basis of effects like ice or larva - anything that needs an irregular surface to start with.
