What's wrong with them being Aero? Aero is -way- better than any of that windows 98 ugly rubbish, no one's going to make themes for that anymore!
That said, I only use one theme so far, and it includes backgrounds I made myself. But the person used as a subject in all my designs is not someone I want to plaster all over the net, otherwise I'd include my theme here. =S maybe I'll make a version of my backgrounds without the subject at some point.
