These sweet hidden scotch coffee mugs change according to the temperature of your beverage. Choose from either Pac Boy (I'm a Pac-MAN Dammit!) or Space Intruders. Intruders, eh? Does that sound foul to anyone else? Anyway, that's enough anal space references for one day. Bottom line is, these mugs are a hell of a lot cooler than the ones we currently rock at the office.
