Halo3X is an open-source 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.
JERRODHO At this level of detail, it'd be cooler as a dashboard widget.
With access to more of Bungie's awesomely detailed stats, and with the added value of some new way to look at them, organize them, or whatnot (show me my "best" games with friend ABC in them, sorted by K/D spread, etc.), this could become cool.
Keep working... I'll keep an eye on this. :-) (Version 1.0)
