From io9, this is a wonderful little video about a little girl who follows a fox who has stolen her metro ticket into the world beneath the surface.
Jacob Wyatt's short animation Metro begins with a very mundane problem: a girl having trouble navigating the subway platform. But when a fox steals her metro ticket, she follows it on a chase through the secret world that exists between the subway platform and the surface world, filled with both expected and unexpected views. And when she reaches the fox's final destination, she'll be glad that the critter stole her ticket.
