Piano stairs to a better world

Doctors have been telling us to take the stairs instead of escalators and elevators to improve our health and feel better, but that's rarely the case. Spend any time in a subway station and see for yourself. The fun and inspiring people at TheFunTheory.com decided to see if they could change that. Their site is dedicated to the idea that the best way to change behaviour is to make it fun, "be it for yourself, for the environment, or something entirely different, just so long as it's change for the better".

With their Piano Stairs installation they were able to pump some life into the otherwise joyless task of ascending a staircase and experienced a 66% change of behaviour. See how a little hard work and engineering know-how can change the world.
