The Digital Water Curtain works as a 'water plotter', computer controlled that displays graphics, patterns and texts, by switching fast acting valves on and off. This produces falling segments of water that serve as pixels, creating a surprising display that constantly scrolls downward.

The water curtain nozzles are designed to create a video projection quality water screen. This feature introduces an interesting new application for the digital curtain with the possibility to combine the graphics and patterns generated by the falling water graphics and the images projected on its surface. The water effects combinations will enhance the visual performance, the interactive possibilities and the aesthetics of the water curtain when combined with video projection. The water curtain becomes an attractive, large and interactive video display.
