๐ฟ L-System
An L-system (Lindenmayer system) is a formal grammar consisting of an initial symbol string and a set of rewriting rules applied repeatedly and in parallel to every symbol, originally devised by biologist Aristid Lindenmayer in 1968 to model plant growth. Interpreting the resulting strings as turtle-graphics commands produces realistic branching plants and fractal trees.
