Scottkuma worked feverishly to:

learn Apple OSX Programming and...
put together a geohash calculator for the Mac.

Installation:

It's a normal mac application - drag it to your Applications folder, OR just run it from inside the DMG. I think I compiled it as a Universal Binary. If you can't run it on a particular system and/or version of OSX, please let me know.

Usage:

Start by entering your graticule's Lat/Long numbers. The given numbers are for Cincinnati, Ohio.

For today's graticule, just click "Generate!" For dates in the past (or the near-future, for Saturday & Sunday graticules), select the date on the calendar, then click "Generate!"

Known bugs:

Requires a valid network connection; locks pretty good when one doesn't exist.
does not calculate east of -30 correctly for dates prior to 5/27/2008
window doesn't lock its size like I thought it would...

Planned enhancements:

will allow for saving of a known "home" location
will calculate distance & bearing to a known location
will calculate same for adjacent graticules to find a closer geohash
