Hi,

that's what L-Systems is all about, at least what P. Prusinkiewicz has published
about the growth of plants and trees
(http://algorithmicbotany.org/papers/#abop).

The syntax of L-Systems is 'alien' - to put it mildly - but to create patterns
or simple branched trees or plants in 2D - that's the easy part of the game.
The tough part and where I'm stuck now is to persuade Povray to produce
something in 3D. That makes my tiny brain burn.

@BE Sorry for misusing your threat to keep the L-Systems banners high.
Love your semiregular pattern doodles.
Here a regular pattern doodle - of course L-System!
