Browsing through internet, I came to this wonderful tool called Wordle which generates a tag cloud with different orientation and effects. It takes input as plain text or your blogs/websites rss/atom feed or your sites URL and generate a cool tag cloud of the words that it encounters on your site. You can change the font and effects on this tag cloud. Also you can remove unwanted words from it.
I tried several URLs and following are the Wordle generated by this site.
