Fractalius experiment
I used Frac on one layer and blended the frac layer with a normal layer using Hard Light i think? It was late...don't quote me on that.
The second one is the same thing but with one of the other Frac presets, Lines I believe. Again, no quoting.
I have found that making a dupe layer, applying frac to the top layer then apply a little transparency to the top layer produces a pleasing effect by bringing mack some tonals from the bottom layer
