An algorithmic plant viewer.
This was simply an exercise in implementing a Lindenmayer System, which is a formula for describing the fractal-like growth of multi-cellular organisms using an alphabet mapped to a set of production rules.
After writing the system, I toyed with generating already-known axioms (the initial seed string for the fractal pattern) defined by Lindenmayer, as well as designing my own.
