fountain displays time

The city of Osaka in Japan recently took the wraps off the largest shopping mall in the country, and it features a nifty fountain that can display the time as well as artwork with drops of water.
I suggest you go to the video to see how it really works. I was hoping that the images and words that you see in the photo to the left were stable, but they are not. For some reason, anything projected here has be cascading like the water falling.

Functioning almost like a “water printer” that displays, not only the time, but intricate Japanese-style flora patterns, Osaka City Station’s water fountain technology is fascinating to watch.
