Orkut launched Themes for orkut addicts

Orkut officially launched orkut themes which are still not live for all users, but you can choose from different themes depending on your choice even if your profile has not been provided by this feature yet.
Orkut themes seem to be similar to iGoogle themes, so the most of them were created for iGoogle.

If the new feature isn't available for your profile yet and you want to see the new themes, you can install Greasemonkey userscripts from Orkut Plus blog to have a feel of orkut themes.
