Here is a new tool created by the makers of Wordle. Tagxedo turns words — famous speeches, news articles, slogans and themes, even your love letters — into a visually stunning tag cloud, words individually sized appropriately to highlight the frequencies of occurrence within the body of text.
With Tagxedo, you can:

• make tag clouds in real-time, and respin, and respin to your liking
• save the tag cloud as images for printing and sharing
• look at all variants of the clouds in a gallery, and pick the one you want for further tweaking or saving
• choose from many different fonts
• use local fonts (e.g. downloaded from Font Squirrel or your own hand-drawn fonts)
• quickly switch between different colors and themes
• constrain the cloud to selected shapes (heart, star, cloud, oval, etc)
• use images as custom shapes (e.g. Reddit Alien) [premium feature]
• use words as custom shapes (e.g. “USA”, “Love”, “Joy”, “I LOVE YOU”)

Have some fun creating with this new tool!
