Researchers at Carnegie Mellon University have found a way to create three-dimensional images using a projector and layers of water droplets. The water drops in curtains, while the projector switches up what's being displayed on each layer, creating volumetric 3D that, because it exists in actual 3D space and not on a screen, doesn't even need glasses.
Thats a pretty nice display i wonder what the possibilities for this are.
