This application will calculate daily Geohash coordinates on your iPhone. Geohashing is a Spontaneous Adventure Generator, brought to you by the xkcd webcomic, at xkcd.com. For more information, visit www.xkcd.com, or check out this application's website.
Geohash now has the capability of mapping the location for your current graticule as well as the graticules immediately to the north, south, east, and west of your current location!
Thanks to Scott Pettigrew for help with the hash algorithm, and, of course, thanks to xkcd.com for a great comic (and...err...the icons too!).
