This is one of the most interesting things we’ve seen in a while. At Osaka Station City, Japan, a water fountain has been built which tells the time. The mesmerising display consists of collapsing water which forms a fluid digital clock every minute. Between each minute, the water forms into moving floral patterns and falling shapes.   The fountain clock works using a digitally controlled printer that outputs illuminated water droplets, creating a liquid manifestation of images stored on a computer. Watch the clever system in the video above. Clocks just got a whole lot cooler.
