I found this today...
here. There are a bunch of them all created by Michael S. Den Beste with Photoshop. I love them. I have read every single Calvin and Hobbes comic. And I much prefer seeing Calvin like this than seeing him on the back of nearly every big pickup truck peeing on the brand of another pickup truck. (Hasn't that gotten old yet?)
Anyway, I love these.
And now I have a new desktop wallpaper.
