New York City's subway system is full of unpredictable excitement. Most of the action happens inside the trains, or at least on the subway platforms. Dean Peterson, however, decided to explore a quirk that people encounter as they're leaving the subway station: a single step on a stairway that's a fraction of an inch higher than the others. It's just high enough so everyone trips on it.
IKEA has installed furniture vignettes in four high-traffic metro stations in Paris. [For those in the know - Champs Elysées Clémenceau ligne 13, St Lazare ligne 12, Concorde ligne 8, Opéra ligne 8]. Each display includes several sofas, lamps, and large prints of IKEA interiors. From the looks of it, they totally transform the normally drab subway platforms.
