This example of a musical staircase is brilliant - and there are more fun ideas on the Volkswagen initiative /www.thefuntheory.com website.
Take the stairs instead of the escalator or elevator and feel better is something we often hear or read in the Sunday papers. Few people actually follow that advice.
Can we get more people to take the stairs over the escalator by making it fun to do?
I get the feeling very few of us are having as much fun as we should be. The recession and two long hard winters in a row haven't helped. So if any of you have any fun ideas - just get in touch. We will be up for it!
