Hattip to View from W6th for turning us on to Wordle, an online tool for "generating 'word clouds' from text that you provide."
You can type in the text you want, or enter the url of any website -- Wordle parses it, giving prominence according to word frequency. Once your cloud has been generated, you can play around with layout, font, and color variations.
Here's what a word cloud of LilaTovCocktail looks like today. (Keep in mind that if you type in the url of a blog, Wordle will parses only the posts that currently appear on the blog's home page. In the case of LilaTovCocktail, that means the 3 most recent posts.)
Created by Jonathan Feinberg, Wordle is free; the only caveat is that if you use a screen-capture or other image representation of the word cloud you create, you must attribute the image to http://wordle.net/.
