(Video) 3D Tetris On A Waterfall Display System
Scientists use cascading water droplets to create a 3D multilayered computer display.
A team from Carnegie Mellon University has created a multi-layered computer display for playing Tetris (or viewing/playing any other content) using sheets of cascading water droplets. The scientists projected the high resolution images onto a series of water screens, one behind the other, to give depth to the image. They said that by quickly switching between images, a projector can display on different layers at different times on this display.
