Holograms

This post will delve less into video games and more into science fiction. Holograms are often shown in sci-fi movies and tv to show futuristic technology. Holograms are usually depicted as images created purely by light. Currently, we have digital projectors, able to display a color image on a flat surface. However, most holograms in pop culture have a 3d image. This would be difficult to accomplish realistically, since in order to create a 3 dimensional image, the light would need something to refract off of. The same way that a laser pointer will show a line through smoke or fog, but only shows a dot through the air. Creating a 3d hologram would require that light be refracted in specific regions in order to create an image. Figuring out a way to do this for a moving image, especially at a high framerate, would be difficult. I hope that one day technology advances to a point where I can see this happen.

What if it were only created in a specific space, such as inside a cube filled with some liquid that could have its density changed rapidly? Either that, or use some light emitting device to outline the image, then have it emit the light and move as necessary. Do you think either of those could work?
