Not long ago, I went down the rabbit hole of space-filling curves, and learned about an obscure paper by Rolf Niedermeier, Klaus Reinhardt, and Peter Sanders that introduced a rather peculiar curve with an unfortunate name: H-curve [1]. The paper mentions that H-curve preserves better locality properties compared to Hilbert curve. It fills the space with H-like shapes, hence the name. Also, like the Moore curve, it generates a loop.
Space-filling curves are ridiculously easy to implement with L-system rules, and I spent a few days developing a set of axioms to express it in a rewrite system. This was a fun puzzle [2].
A => BF-F-BFFFC-F-FC+F+BF-F-BFFFC-F-FC
B => BFFFC-F-FC+F+B
C => C+F+BF-F-BFFFC
