Ars Technica takes a look at a recent breakthrough in projecting dynamic holograms which can be viewed from a wide variety of angles.  This has been something which has been very difficult to achieve, for reasons which Ars articulates, but which researchers have managed to accomplish with the use of clouded glass.  You usually see that type of glass used to obscure light, for instance to offer privacy when in the bathroom but when designed correctly it can instead act as a large number of lenses project a focused holographic image. There is still a lot of work to be done to scale the holograms to a size and resolution which would be attractive for commercial usage but you can read up on the current state of the research if you are curious.

"Sometimes it amazes me how fast physics goes from fundamental ideas to producing a new toy. The latest example comes from a bunch of experiments and theory on how opaque materials affect light passing through them, a topic that we have covered extensively in the past."
