"Halo3X: A Halo 3 Stats Manager for Mac OS X"
Halo3X is a bungie.net parser that automatically looks up a gamertag and presents its Halo 3 data in a unique way. No more waiting for bungie's pages to load in your browser! Halo3X is written in Objective C, using Mac's Cocoa libraries, resulting in a small, compact application.
Can be downloaded here. Halo3X is an open source app. I release it under whatever license says you can't sell it. Source can be found in this directory.
