Hilbert curves are fairly simple in an LParser, the rules in the book consist of straight forward turns and local x axis translations and LParsers don't really recurse to generate the rules they're more iterative building by replacement which helps.

That is a 3D Hilbert curve, right? I had a discussion some month ago, about whether it is possible to generate such a curve in Structure Synth. I think it requires a system with slightly more expressive power (such a an L-system), but I'm not completely sure. Nice! That is a 3D Hilbert curve, right?
