Wordle - Beautiful Word Clouds

Picture on the right is created with Wordle.
Input was this blog. In their own words:

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.

Gives very nice impression what it is all about. E.g. you can use it on your own c.v. and include this at the beginning of your c.v.
