"Hairball (Shadows)"

Left-click and/or drag to spawn particles
Right-click to clear

I really like Xavier's original sketch...
This is just some playing around I did with it after
he posted a message in the Processing forum looking for some
help with it. Main changes I made were restructuring the trig tables,
adding "shadows" (aka emboss) to the rendering, and adding a small
"margin" so that evolution wouldn't stop so hard at edge.
