Ha. I'm starting to catch on. I do know what a gradient tool is. That's what my teachers used when I was in school. Their pens and pencils were always breaking under the extreme stress and pressure. Unfortunately and oddly so were my teachers. Anyway, I digress. They used a gradient tool to scratch F- on my tests and papers.
Regarding Apo Fractal, PBS had a great show on fractal that I watched last night. As nearly as I can understand from that show, your posting is some sort of math equation.
I'm not sure where the title fits into all this. I'll have to get back to you.
Nicely done mate
