Play Tetris on a 3D Water Display

From Researchers Peter Barnum Srinivasa Narasimhan, and Takeo Kanade at Carnegie Mellon University comes this waterfall display which synchronizes droplets of water that projects images onto a series of water screens, one behind the other, to give depth to the image.

Each screen is formed by water droplets falling from 50 stainless-steel needles. The needles release their droplets in unison, with 60 such lines created every second. A camera tracks their position and feeds the information to a projector, which illuminates them with pulses of light. The human eye integrates the information from several pulses to create the illusion of images moving on a floating screen.
