Came across this wordle site today. Interesting way to look at a text's content. Input your text and see the "word clouds" formed by this novel toy. The image's appearance can easily be tweaked. If you want to save your image as a picture then do a "printscreen", crop with your picture toolbar and save as a picture. Could make a nice opener / background slide to a presentation when talking about what the presentation is going to cover.
