Wow, I've bookmarked the article for future reference, this is all very cool! I have been working in OpenGL recently on procedural meshes, particularly with L-Systems. My method for drawing branching structures was basically the same as the "Extruding" action the article talks about. The rotating of the splines around an axis is very clever! I am definitely going to use that.

L-Systems are indeed a very good way to get started. We didn't mention it in this article, but it could have been part of the first section. Our demo with cubes intensively used L-systems to organize and animate the cubes (it was briefly mentioned in the making-of - https://www.ctrl-alt-test.fr/2010/behind-incubation/).
