Piano crosswalk

Challenge
Promote visually and audibly the Salzburg School of Music right in the middle of a city.
Solution
Crosswalks were repainted in a piano keyboard shape at different locations in the city. Sensors were also installed beside the crosswalks on the sidewalk. Every time the walk sign turns on a piano song starts playing, simulating the idea that the people who start walking through the crosswalk are playing the song by stepping on the crosswalk.
