Theory of Fun, Volkswagen’s Piano Staircase

Attempting to move people from using the escalator back to the staircase, Volkswagen supported the implementation of working piano keys on the subway station steps on Odenplan, Stockholm. As the images show, just the fun of it lead to a more than 60% decrease on escalator usage.
This was the first initiative on a series of events under the subject ‘Theory of Fun’ which Volkswagen supports, defending that attitudes and behaviors can be changed if things are fun. All the details can be found at
