Pythagorean WIndmills
Hana Murray and Simon Gregg have been having this amazing discussion of Fermat's two squares theorem, inspired by Mathologer's video about it.
They have been doing a great investigation into these windmill numbers, so I made this, which is less satisfying than Cuisenaire rods, but still pretty.
