I'm running it right now, and haven't yet seen a single resulting artwork, but looking at the examples, I immediately hate the typical UI hotspots, like the top left (or top right) corner, toolbars on the left and such. I'd process the captured mouse coordinates and add a steady rotation to them (when the mouse is in motion), thus turning the art into a more abstract square (or circle, if you wish) form. Somewhat like the polar coordinates graphs, some of which are really cool.
