Bluetooth: tenth-century king Harald Bluetooth united dissonant Danish tribes into a single kingdom. (re: uniting communication protocols)
I guess it's not so surprising bc why the heck is it named after a tooth (had been thinking... the shape of a Bluetooth dongle? Lol) but still, this is a pretty obscure ref.
H3 is similar and cool, but this builds a similar nested grid concept around latitude/longitude, which can map to existing coordinate systems and database storage.
Also note that population density affects how effective a given precision "blur" is for an area; we're also hoping to develop a web service or library to roughly return population density for any given region of the globe.
For simpler fisheye and defisheye effects, I wrote this web based tool a few years ago which some may find useful!
