This has been around for awhile, but by happy accident discovered or rediscovered making Wordles. They are artistic word clouds, basically. You can save these and print them, create t-shirts, mugs, etc.
I used the address of our happy blog here to randomize our vocabulary. If you click on the thumbnail, you'll go to the Wordle site.
I'm providing a bigger, better screenshot picture of the Sioux Falls Cartoonist Blog Word Cloud.
