The Hilbert Curve

ABF+AFA+FB,B+AFBFBFA+A \to {-}BF{+}AFA{+}FB{-}, \qquad B \to {+}AF{-}BFB{-}FA{+}
Cool Fact
Unlike Peano’s curve, this one never revisits a point, and its quadrant ordering gives it unusually strong locality — which is why real systems (Uber’s H3, Google’s S2) use it for spatial indexing.
