The decimals generated by the geohashing algorithm can also be used to generate a single point on the globe instead of one for each graticule and this award celebrates those lucky or mad enough to pursue that single point.
To generate this point take W30 decimals for a date (to make it global) and multiply the latitude by 180 and subtract 90, and the longitude by 360 subtracting 180. This will generate a single point on the globe which is today's only globalhash.
Proof is the same as any hash, but at the single day's coordinates. Good luck! The odds of the globalhash falling in your graticule are 1 in 64,800!

Example
On September 9th, the W30 decimals generated were 0.007297279839462378 and 0.41303791404189066 for latitude and longitude respectively.
0.00729727983946237 * 180 = 1.3135103711 - 90 = -88.686489629° Latitude 0.41303791404189066 * 360 = 148.693649055 - 180 = -31.306350945° Longitude
Or 88.686489629° S, 31.306350945° W which is quite close to the south pole.
