Here are a couple of Kindle screens I made using Wordle’s free word cloud web-app. To be honest, I’m still undecided about whether the cartoons add too much clutter, but I thought these two were fun regardless considering the subject matter.

You can make your own text-based screensavers at Wordle.net.

Update:
These screensaver images and others are now collected on the Free Screens page of the site.
