Making it fun to walk

Volkswagen has an initiative where it is trying to get people to walk and take the stairs more for health benefits. This video shows what happened when they turned a staircase in to a piano. People took the stairs! 66% more according to them. There is no question that urban design matters. How to work it into policy is less clear, but these inexpensive ways to make walking fun and give a unique status to train stations (or neighborhoods) are well worth pursuing.
