Voice Tank

Ripple tank controlled by polyphonic pitch detection actuation. When two participants speak into intercoms, their voices are analyzed and converted into notes. Motorized components located on both ends of a water tank hammer these notes onto the water’s surface. The resulting waves interact and create unique patterns and shadows on the water’s surface.
