AquaLux 3D: Text, video, images, and even Tetris on a multi-layered water display

I recently came across the INAVATE website, and I've found several articles on topics that I'm sure will interest my blog readers. The article that intrigued me today was about the AquaLux 3D project by researchers at Carnegie Mellon University. In the videos, you can see how text, video, and images can be created with light and water droplets. The researchers used this technology to create a multi-dimensional Tetris game!

A Multi-Layered Display with Water Drops (non-technical version)

"Using a projector and rows of water drop emitters, we create a multi-layer display that can be used for text, videos, and interactive games."
