I think the original idea is from Paul Bourke. He calls it a Spiral Honeycomb Mosaic (SHM).
See his "Tiling on The Plane" page [1]. Scroll down to the section titled "Hexagonal Lattice" (contains links to source code with coordinate conversions).
Here is a Rust implementation of a different variant of the same idea [2].

There's so much more to add to the page, and I keep adding over time. Thanks for the link to the hex-spiral crate; I'll add it to my bookmarks.

> Spiral Honeycomb Mosaic [0] (search the page for "Spiral Honeycomb Mosaic") is an interesting way to assign numbers to hexagons in a hexagonal grid. It results in bizarre properties.
