Wordle is a wonderful tool to create effective and visually appealing tag clouds.
You can create tag clouds based on list of words, URL of any blog or RSS feed and based of a del.icio.us user name. A random tag cloud will be created and then you can change setting such as font, layout and color.

Many people discovered this tool and as of today ~1900 Wordle created maps were uploaded to flickr. See a slide show:

Created with Admarket’s flickrSLiDR.

With the tool, I created few Tag clouds for my activities. it will be interesting to see over time how the clouds change.
