Now this is pretty clever ... Halo & Sprocket creator Kerry Callen shares a comic configured like a crossword puzzle, which he created with his son Martin. Callen said it came to him in a dream -- how cool is that? I'm impressed with how he used the same panels to tell different stories.

"Like Scrabble, the tough areas were where something had to work when two squares inconveniently touched, such as the 'Love is the solution.' touching 'What about overpopulation?' There's a joke there, but it doesn't jump out at you," he wrote on his blog. "I'm thinking this has the potential to be a fun challenge for cartoonists, much in the same way a '24 hour comic' is!"
