This really helped me make sense of certain Lindenmayer system rule sets. Thank you!

[@CforCoconut]

The animations are very helpful. Thank you so much!

[@Geotechnogeek]

Excellent animations and explanation!

[@葉佾宸]

is the 42 axis same as 21 axis?

[@Ilovecomedy7]

I don't think so. 42 axis will have 90 deg rotation while 21 axis involves 180 deg rotation.
