The Water Wall is a water-droplet based display. Visitors can draw designs on the two touchscreen kiosks, and their drawings are then displayed as droplets of falling water. When idle, the display cycles through pre-programmed images of flowers, raindrops, and geometric shapes. 144 individual solenoids, driven by a microcontroller attached to one of the kiosks, control the falling water.
