Display this animation full-screen when they ask you to open your laptop during a security check on the subway.

**Under no circumstances should ANYBODY use the previous animation when they ask you to open your laptop during a security check on the subway, or in any other manner during which the display of the animation could be interpreted as a hostile act. Please defer all legal action to Penn & Teller, who gave me the idea in their 1997 book, “How to Play in Traffic.”
