Some really nice entries here, thanks everyone for contributing. I really like J.Edward and Domino's entries at full res, but a lot of the detail is lost when they are downsized. Ilanthar's idea is really unique and cool, as one might expect. However I'd have to say that just looking at the smaller size icons my favorites would be between Chick's entry and Ariz89's entry. They both scale very well (my only nitpick with Ariz89's entry has to do with the color scheme - the gold looks to "yellow" rather than gold).

Cheers,
