heres another theme i got that i like called GlaskGlart HD - it was free, not crazy about it still, the background is from the creator dudes site i think. (got it myself)
but still my favorite theme although totally not fluid, or finished that i installed manually by uploading the folder and making some tweaks, is this guy, i just love the icons (mostly the ones on the dock), but its really just icons and the same background wallpaper:
