L-Systems interactive

Main subject is an applet to try out Lindenmayer's language. Type in the parameters and watch the result after pressing return or clicking the update-button. If you don't know my version of his language, use the change figure-button to view the examples first. Look at the symbols list and get more information about the L-system (page 2).
