My favorite wallpapers come from guy called Vlad Gerasimov and his site http://vladstudio.com/. I randomly chose 5 wallpapers (1680x1050) and made themes from them. You can try them or make your own. There is a tutorial on dev.opera.com.
Enjoy!
Bluebells
Eagle Ray
Learning to Fly
Lightnings
Whale

Well, I paid the guy for the premium account and I don't sell it or anything. But yes, it is still a copyright violation. That's why I haven't submit it to the official themes catalog.
During Halloween he sells the premium account for $2 only (one payment per life). So If you want to use this themes and also have good feeling you can buy it
