[edit] Geohashing coin

Geohashing coin

Inspired by Relet, and building upon Dawidi's work, I've designed this geohashing coin that you can make at home.

The source files can be downloaded from Thingiverse. There are also more pictures there.

I plan to "release" some of the coins that I've made into "strategic locations" to promote geohashing. When I do so, the coins will have a tracking URL on the reverse.
