Also known as the "Ulam Spiral" for Stanislaw Ulam who discovered it by accident in 1963, supposedly while doodling during a boring presentation.

This page is great, but the wikipedia page is too and provides other related work and coincidences. https://en.wikipedia.org/wiki/Ulam_spiral

No, actually the Ulam Spiral is something else, a simpler spiral to create. Still, I too recommend the Wikipedia page.
