I would like to thank my friend Gretchen Thompson for this
cool web tool called Wordle, which she wrote about on her blog.
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.
I've made a couple and use them as desktop wallpaper.
