I wrote a very rough GUI for my L-system during these days. This GUI can verify the strings of rules inputting by a user. Some of the procedures may not validate variables perfectly. I am still working on that. If you want to try it, please copy both scripts into the default MAYA script folder (../maya/7.0/scripts) and copy the picture into the icon floder(../maya/7.0/prefs/icons). Be careful, this is a work in progress.

Using another rules can create different shapes with this script.
