If you're interested in L-systems you may also enjoy reading about Shape Grammars. Sort of an evolutionary dead-end in terms of system design, but intriguing. As far as I can tell they were basically superceded by other types of programmatic or parametric design systems.

L-Systems are still usefull in plant science if extended a bit. Here a software package one can try: http://www.grogra.de/ http://www.grogra.de/

  This is great, thank you. Do you actually use this software? I’m very curious to hear about real world applications of these generative systems.

This is a fantastic collection of links and makes me wish there were one modern site that summarized all this work, maybe with a working Javascript demo.

  That's on the long list of blog posts that I've never written. Feel free to start with these and go forward! Make sure to get a physical copy of Shape, it's one of the most baffling textbooks I've ever tried to read.

Thanks for sharing, I never heard about this before! The Wikipedia article on shape grammar has a link to an old website[1] from a workshop at MIT that links to many more interesting resources, including the “Shape” book by George Stiny you mentioned as a free download (not sure if the author agreed to this, so I’ll just use it as a reading sample and buy the book if I like it), course material, presentations, etc. I also found a more recent book[2] by George Stiny called “Shapes of Imagination: Calculating in Coleridge's Magical Realm” that is also about shape grammars and is actually open access. Coming from a design background, I am sure to take a closer look at some of this stuff. - [1] https://web.archive.org/web/20190405160829/http://shapegrammar.org:80/ https://web.archive.org/web/20190405160829/http://shapegramm... - [2] https://direct.mit.edu/books/oa-monograph/5489/Shapes-of-ImaginationCalculating-in-Coleridge-s https://direct.mit.edu/books/oa-monograph/5489/Shapes-of-Ima...
