An LED light is pointed to a water surface, which casts its reflection to a wall, where 12 light sensors positioned on a grid are monitoring the brightness. In the room, there are 12 piezo buzzers hanging from the ceiling, arranged on a symmetrical grid around the water. Each light sensor modulates the pitch of a single speaker. If you wash your hands in the bowl, the light starts trembling on the wall, and the electric crickets start chirping in a different tone.
