If this floats your boat then the inimitable Vi Hart has done a series of videos about space filling curves and related matters:

Nice!

Be sure to check out shape grammars for non-organic procedural content generation; for example, the classic "Procedural Modeling of Buildings" from http://peterwonka.net/Publications/publications.html (as well as many other great publications from that author).

I took a class by P. Prusinkiewicz (Dr. P) at the University of Calgary as part of my graduate program more than a decade ago. Still remember it fondly and keep all my presentations and slides from the coursework.

Unfortunately I don't think I did very well as I was very headstrong and rewrote the C++-based L-system generator in Haskell. That didn't get me any extra points :)

And just because it's Christmas time:

Would be interested in a simple L-system Javascript example.
