L-system trees tool

An adapted version of a math assignment. Just for fun. You can try to set the rules yourself.

If you don't know what rules to set, here are a few rules for you to refer to:

Axiom  : X

variables : X 

variables rules  :  F+[[X]-X]-F[-FX]+X

variables : F

variables rules  :  FF

Iteration: numbers from 2-6

Axiom  : X

variables : X 

variables rules  :  [*+FX]X*[+FX][/+*F-FX//F]

variables : F

variables rules  :  FF

Iteration: numbers from 2-6

Axiom  : X

variables : X 

variables rules  :  [F/[+FX][*+FX][/+FX]*F]

variables : F

variables rules  :  FF

Iteration: numbers from 2-6

I hope you can create more regular and beautiful trees with your own rules.
