Lsys – Fast and interactive L-system generator written in CoffeeScript

If people are not familiar with L-systems, wiki is a good place to start: http://en.wikipedia.org/wiki/L-system

Besides their inherent interest in modeling biological systems, people here might be interested in them as an example of a stochastic grammar, i.e., a system of rewriting rules where multiple branches can be taken with various probabilities. L-systems are not necessarily probabilistic, but in applications, probabilistic ones are often used.

This is great--I love stuff like this. There's also CFDG[1].

I noticed a drawing problem in Firefox and submitted an issue[2].

A lot of the examples are much more impressive when being rotated with the mouse, they produce some pretty crazy patterns. Take a look at the Dragon Spirograph and Dance for me.
