wordle

At wordle.net you can create a "word cloud" out of text that you type in, or you can give it the URL to your blog, and it'll pull random words and make a cloud of those. It was kind of fun to play with. Interesting to see which words it picked. (It seemed quite fond of "pretzels"--I think it has to do with word frequency.) It kept giving me the same random words, though, so to get some variation I tried it after a few different posts.
