It might look like this.

Toronto-area animator Adam Brown is the man responsible. This is the original strip he used as inspiration. He didn't animate the entire strip, because to do so would mean he would have needed someone to voice Calvin and Hobbes, a prospect that made Watterson himself sort of uneasy.

Of course the internet is clamoring for more (which makes all sorts of sense, considering how well this was done) but I kind of hope he doesn't. I'm sure the guy who made the first Calvin bumper sticker had the best of intentions, too.
