I first encountered this composition in the form of Reinder Nijhoff's sketch on Turtletoy: turtletoy.net/turtle/25b7bc4d43. I was immediately in awe of it (and quite ignorant that it was originally a 1952 Escher composition). It took all my 3D explorations throughout 2022 before I had a good intuition of what's going on here.
And now it's time to reproduce it, because I can! I also used this sketch to dial in my canvas-based line hiding method built around a Three.js renderer.
