Un bonito y sencillo trabajo de Daniel Hirschmann que convierte unas escaleras en un instrumento musical, transformando el serio transito por las escaleras en un juego. En la página del trabajo se puede ver la documentación en varios estados de desarrollo.

Tuned Stairs

On each of the stairs is a matt-switch which activates the instrument-playing mechanism attached on the outside of the banister. The armature is made of steel with a pull-thust solenoid attached to it. Above the solenoid is a tuned resonating bar facing down. As the matt-switch is activated, the solenoid momentarily strikes the resonating bar - resulting in a soft delicate sound resonating through the local area. The matt-switch’s signal gets fed into an arduino board which then activates the solenoid mechanism through a transistor circuit. Each arduino has its own conduit board built to easily connect the switches to their corresponding solenoid mechanisms.
