Spent an hour in the park last night ramping up the remix of older sketches.
Here's a result combining three of them: there are about a hundred bezier curves at the very back blurred beyond recognition to create a texture, then I place a set of larger marbles and one instance of the hexagons and blur the heck out of them, then I layer up a few more sets of marbles, and finally I drop in sharp hexes overtop the blurred ones for that fun glow effect.
Also, I did a 1:20 screencast of the sketch generating different configurations realtime so you can see that there's a certain amount of editorial control thrown in with all the computer-generated randomness. (It's slightly slower because it's running alongside the screen capture software, but it's not all that quick to begin with thanks to applying four blur filters during each frame.)
