A formal grammar that recursively outputs symbols and strings of symbols based on a set of production rules in order to represent geometric shapes and patterns. An initial symbol or string is used as a seed to create a new string; this new string is then used as the seed for the next group of symbols. Symbols representing line length, line angle, and scale can be used to easily represent geometric patterns that are fractal. L-systems are named after the botanist Aristid Lindenmayer who pioneered their development and used them to categorize the algorithmic structure of plants.
