    The flowsnake design at work! I daydreamed about building that into OSMAnd for mapping and I’m delighted to see someone did just that.

    Edit: I wonder how they deal with the errors where the borders of a refinement don’t match the parent hexagon (zoom levels don’t tile perfectly). I see they’ve chosen 7 for their Löschian number to minimize it, but the dev docs don’t go into design rationale much.
