Piano Stairs - Using fun to change behavior...

This is a great little project that shows how invoking "fun" can be a useful tool in changing peoples' behavior. It starts with the problem, clearly showing how people tend to prefer an escalator over an adjacent staircase - thereby consuming extra electricity and missing an opportunity to get a bit of exercise. The mischievous crew behind the experiment then outfits the staircase too look like piano keys and wires them to play each note as the stair is stepped on. A charming video montage later, practically everyone is taking the stairs. I'm sure that some users play around on the stairs and block traffic a bit, and I'd be surprised if there weren't a few collisions here and there - but the project makes people happy and changes behavior for the better. That's win-win!
