Piano Stairs

My first time using stumbleupon.com and I find this brilliant video. In an attempt to encourage people to leave the escalator alone and use the stairs this group red designed them to look like a giant piano. Every step makes note as you ascend - 66% more people used the stairs while this experiment ran.
