Piano stairway promotes healthy lifestyle

The "piano stairway" is a playful, interactive musical installation that went live last week in a subway station of Xi'an, Shaanxi province. The stairs, painted black and white like a piano keyboard, make a musical note with each step. The idea is to encourage people to use stairs more often, rather than escalators. Online comments show that commuters are willing to change their lifestyle when exercise is fun.
