L-System


An L-System in javascript & canvas. You can use a drop-down box to alter which fractal is drawn and how many iterations to perform.

An L-System is a way of describing self-similar fractals, like plants - it works by changing symbols according to rules and performing multiple iterations.

To display, the final string is interpreted by a turtle which uses them as instructions (eg go forward, turn left, etc)

The wikipedia article is worth a look, it is where I got the axioms & rules from.

Warning: If you alter the values and set them to high it may freeze your browser

UPDATE: L-System version 2
