A piano staircase or an escalator, which would you choose?

piano, stair, escalator

If we make taking the stairs more fun will more people choose it over the escalator? That’s a question the people at thefuntheory.com (an initiative of Volkswagen) asked themselves. They are trying to see if they can get people to change their behaviour for the better by making them have fun. The videos they made for this project are spreading quickly all over the web.
