Space Filling Curves Lindenmayer System

For a project in the university I searched for different Space Filling Curves and Fractal especially in 2D. I programmed some things with Python based on the L-System by my own to understand it better. I know theres an Add-On called "Morphocode Rabbit" but they  only deliver a Plug-In to draw the codes.

What I´m searching for right know are more F-Codes for fractals an space filling curves. I´m not that interested in plant like fractals. If you know some codes I didn´t used right know or if you know where I can look some more codes up, please answear me. My GRasshopper Module is attached! Feel free to use it and varyfie it. But be carefull with hight numbers of iterations.

Some exampels are attached too!
