Wordle, beautiful word clouds.
Super simple to use, click the create button, type in a series of words and hit the go button and magical arrangements of those words appear. I will say the only down side is the html they provide for you to put into your blog gets you a very small image, like mine at the start of this post, and you can't save it to your computer. The best option is to print it. Either way it's a fun way to pass some time. Make sure to check out the galleries too!
Enjoy your cloud creations!
