I think the 'The Algorithmic Beauty of Plants'
(http://algorithmicbotany.org/papers/abop/abop.pdf) is a more up-to-date version
of L-Systems.

It's not too much. 2 symbols for pitch up/pitch down and 2 symbols for roll
left/roll right. And some 'placeholder' chars like A,B,...
See chapter 1.5 in the book I mentioned above.
There is also an axiom and rule for the famous Hilbert curve in 3D and a 3D
bush-like structure including images of both.
The only program that covers 3D L-Systems is Lparser by Laurens Lapre but it's
MS DOS only. But I will rummage through the .LS files to find things we can use.
