Lindenmayer L-Systems Rules
Creating turtle fractal art with L-Systems just for the fun
These fractals are created with my free L-System app that you can download here:
First install Python 3.8 for Windows :
http://www.qchartist.net/files/programming/fractals/python-3.8.0.exe
Then extract this zip file in a folder inside your Python38-32 folder :
http://www.qchartist.net/files/programming/fractals/lsystem-master_RQ_Py.zip
Enjoy!
