Green Flag. (Turbo mode, <Shift> key + Green Flag, for much faster drawing). This project uses a Lindenmayer system to generate and draw 5 generations of a Koch Curve. The Koch Curve was used as an example in "Lindenmayer 0" to explain how to draw a Lindenmayer system. The rules used here to produce the Koch Curve are: start string: F++F++F rules: F is replaced by F-F++F-F + is replaced by + - is replaced by - F means "draw forward" + means "turn clockwise 60 degrees" ā means "turn anticlockwise 60 degrees"
