"Wordle is a toy for generating "word clouds" from text that you provide. The clouds give greater prominence to words that appear more frequently in the source text. You can tweak your clouds with different fonts, layouts, and color schemes. The images you create with Wordle are yours to use however you like. You can print them out, or save them to the Wordle gallery to share with your friends. "
Tweetcloud was born out of a project to synthesize meaning from a high volume of short messages. Our goal is to quickly show users "what's being said" across the Twittersphere or from a specific Twitter user through an intuitive interface (a cloud). Enjoy and let us know what you think.
