Ooh, I did this too a while ago: https://eliben.github.io/lsystem/ This has some pre-sets you can examine that draw well-known fractals
+1 for the presets.
Lindenmayer Systems

Re: Lindenmayer Systems
#12I designed and teached a bachelors class in Generative Grammar Structures for few years at Sofia University. And L-systems were part of the curriculum. We also had Chris Coyne’s CFDG and Structure Synth in the classes.
Interestingly l-systems are semi-Thue grammars, not Chomsky grammars and their inventor was a biologist modelling tree growth.
The class made huge impact on everyone’s ability to comprehend discreet math concepts such as state space, regex, FSMs and alike by actually showing these visually. I’m convinced CFdG has to be included in higher school curriculum the same way spatial analysis augments/complements greatly classic geography courses.

#13If 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 As far as I can tell they were basically superceded by other types of programmatic or parametric design systems. Some references:

Re: Lindenmayer Systems
#14Are simple esolangs like BF also L-systems?
Re: Lindenmayer Systems
#15Ooh this is one of my favourite topics :).
I had a side project a while back which has a few fun presets . You can click-and-drag to animate the pattern by changing its branching angle:

#16Here's an Observable notebook with a bunch of examples. [1]

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

This is really fantastic work!

#19I once tried my own L-system generator on lisp! Take a look

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.
