Gmail Themes is pretty cool.

As much as I dislike the idea of being ruled by a corporation someday (although it sounds less bad than being ruled by our behemoth of a government), I wouldn't mind being ruled by a corporation as seamlessly cool as Google. (As leftist as they are. When they're ruling conservatives, they better start recognizing holidays we enjoy, not May Day and other leftist holidays.)

Back to the point. Gmail themes just came out today, and it is about as awesome as you could imagine. Yeah, its just themes. Big whoop. But email is one of those things you check many, many times per day and its cool to have that personalized.
