Pixellated violence can be educational, too

Neat story on BoingBoing about a dad allowing his son to play Call of Duty on the condition that he adheres to the Geneva Convention. Really warms the cockles of my heart (what the heck are those, anyway?) to see a parent finding out what the game is about, and using it to educate his son -- much better than a kneejerk "no-it's-too-violent" reaction.
