For general information on Lindenmayer systems, see [[related Wikipedia article->http://en.wikipedia.org/wiki/L-system]].
The script that I wrote for [[js1k contest->http://js1k.com/2012-love/]] generates given L-system code on the screen. It supports turning (@@+@@ and @@−@@), drawing (@@F@@ and @@G@@) and push/pop (@@[=[=]@@ and @@[=]=]@@) operators.
An L-system code consists of the following lines.
:@@iters[=:=]@@ ''n'': The number of iterations. The more iterations performed, the more detail is achieved and the more time is spent.
:@@angle[=:=]@@ ''Θ'': The turning angle in degrees. For example, 60 or 90.
:@@start[=:=]@@ @@"@@''S''@@"@@: The initial axiom. The computation starts with string ''S''.
:''X''@@[=:=]@@ @@"@@''Y''@@"@@: A rewriting rule. In each iteration all ''X''s in the current string is substituted with ''Y''s.
