The crosswalk is just one of many ways the Polish Institute is celebrating the Chopin bicentennial. It is also organising concerts, exhibitions and an online quiz.
The keyboard crosswalk is the work of Helena Czernek and Klara Jankiewicz, who won a competition invited by the Bec Zmiana Foundation, the City of Warsaw Promotion Bureau and the Department of Industrial Design at the Fine Arts Academy of Warsaw.
The crosswalk can be seen until the end of the year.
