The daily commute in Sao Paulo, Brazil now moves to a new tune. A musical staircase designed to look like a piano has been installed at one of the city's train stations. The steps, 34 of the 42, have been fitted with piano keys that activate with each step. It fills the station with the sound of music. It is part of a project to promote physical activity by encouraging people to bypass elevators and escalators and take the stairs. The piano steps will remain at the station through February 24th.
