I'm sitting here watching the Yankees beat the Red Sox and noodling around with Rob Bunney's L-System trap shapes in One Shape. So I know that the Yanks are winning, I know that CC is still pitching. I also know that working with L-System fractals can be a bit daunting. Rob has made them a bit less formidable by including L-System:Samples which provide excellent starting points for this complex system.
I used some of the organic samples (there are geometric samples as well) on top of a basic L-System tree. It's not the best thing I've done, but it was fun.
