Nudging users to do the right thing!

To encourage people to take the staircase instead of the escalator, Volkswagen converted a set of steps at the Odenplan subway station in Stockholm into working piano keys. The effort is just one stunt that appears on the carmaker’s Rolighetsteorin.se or “Theory of Fun” website, which showcases efforts to get people to change by simply making things more fun.

Anyone who has read "Nudge" will recognise how important this is!
