Iterations

A Lindenmayer system grows a string by rewriting each symbol with a rule, then reads it as turtle commands: F draw, +/− turn, [ ] push/pop. Simple rules, botanical complexity.

Reading this result: After 5 rewrites the string holds 0 symbols — each pass replaces every symbol at once, so detail multiplies exponentially, not linearly.
