What to do:
Specify your rules in the rule text box (axiom : symbols) - 1 rule per line. Input which rule(s) to start with and see what you can come up with! If your not sure whats going on, check out the samples by double clicking them to see what different rules will generate!

You can now use your mouse wheel to zoom in/out!!!!!

Notes: Add more iterations for 2D - but be care with the 3D!
