Ha, yeah, I remember reading about your project back in April (I think someone shared it on the GeoRust Discord). Really cool stuff you have here!

Can't say I understand all the math behind it, as it's not my forte (even for H3, for the more numerical parts, I rely on the work of the original authors: I could never have come up with this myself), but your doc is really great!

For the follow-up article, I hope I can get to it eventually. But spare time is a rare currency ^^
