Take a mind journey with us: You step off of an international flight and walk to the baggage claim areas in Sweden's Stockholm Arlanda Airport or Göteborg Landvetter Airport. You're tired, you're waiting for your luggage, and you have a pocketful of foreign coins. Usually, you'd drop them off in the Red Cross donation box, which takes any type of currency, and you'd continue standing, waiting. Now, the Swedish Red Cross and Swedavia Swedish Airports have turned those donation boxes into classic arcade cabinets -- drop in any currency from any country and start playing Pac-Man, Galaga or Space Invaders before grabbing your bags. It's better than letting those coins collect dust, and classic video games have been scientifically proven* to help travelers shake off that "I've been sitting for 18 hours" look.
