I'm not sure how this one got passed me for so long! If you like Wordle, you'll love Tagxedo.com. It provides you the ability to mold your words into visual shapes like flowers, hearts, President Lincoln, birds, etc. Fun stuff...because we need fun stuff.
Here is my Tagxedo word cloud of my blog. This image shared using the Tagxedo "code snippet." You should know that using Tagxedo requires one to download and install Silverlight (unless you already have it, of course).
Have fun all. :)
