in a competition sponored by volkswagen, the funtheory.com, a group in odenplan, stockholm turned the subway stairs next to an escalator into working piano keys, in turn 66% more people used the stairs, link on youtube. i like this because it plays with our everyday environment, by adding a fun surprise to the typically robot-like motion of subway time. i wonder what people thought about after they left the stairs.
wishing i’d known about the competition! bottle arcade & bottomless trashcan are great too.
