I called home last night and my daughter Molly had an exciting story to tell. She was at her friend Danielle's house (the same Molly and Danielle from the video) and playing the Sims, a computer role-playing game.
One of the characters was using a computer which had an item "Solve the Unsolvable". Danielle clicked the phrase. A few minutes later a pop-up opens and says "Your Sim has made progress on the P = NP Problem".
Nothing like a video game to impress the little one.
