Fractal Tree.
L-system is an algorithm for modeling cellular growth. L system is actually text-based. But I want to utilize it to generate graphics. It involves two things: alphabets, an axiom(the beginning of the L-system) and a set of rules. L system is a recursive way to generate sentences using the same strings over and over again. There are lots of different ways to interpret L-system, such as a poem or a melody.
