For some reason i don't like any of the themes that are on the jquery ui themeroller page (i am looking for something on a business website and these all look either bleak or too corny). I wanted to see if there were other sites where people have uploaded or voted on other themes to view and download.
I know i can tweak my own but first wanted to see if anyone has done this already with a better artistic eye.
Aristo is a really nice jQuery UI theme that is worth consideration.
As others have mentioned, there are more themes out there if want to do some more digging...
