A couple of years ago, Boris Schimanski, a well-known cartoon artist in Germany, set out with the intention to keep his kids occupied with something that would hold their attention and imagination long enough for him to finish his current work project in peace and quiet. He took some plain cardboard, drew a castle and punched out the individual pieces. After his work project was completed, he noticed with interest that the kids were still busy decorating and playing with his cardboard creation.
