Cloudclutter has to be the most unique theme we have ever seen. For those of you familiar with WP Cumulus tag cloud, this theme just looks like a giant tag cloud, with widgets at the side.

The only flaw of this theme is : it is not suitable for a professional website.Other than that, Cloudclutter is clean looking, and also very fun to play with.

Advanced: the theme will display the titles as tags, but you can configure it to show the tags in the cloud. Personally, i think that is a lot more fun. For a example of a Cloudclutter-themed website, go to Freedom Above All.
