The recent waterfall installations in New York will seem just like so much plain old falling water, once you've seen this video of a computer-controlled waterfall "printing out" amazing patterns and pictures. It's in Canal City Hakata, which is a shopping and entertainment complex in Fukuoka, Japan, and seems to work using similar principles to an inkjet printer. Basically a computer is controlling hundreds of nozzles to precisely deliver water drops so that they fall forming a pattern... and that's anything from words to pictures. My faves are the eye-dazzling geometric patterns—they suffer less from the distortion caused by free-falling. Mesmerizing stuff. [Hacknmod]
