Don't kill me, but there are no such thing as Holograms, that can be projected into empty space. Everything you have seen is not as it seems.

In order to see any projected image, it must be reflected off of something. When you see a hologram in person, you are seeing a reflect off of glass or other semi-transparent material, which is based on an old trick known as the "Peppers Ghost" Illusion. If you have ever been to Universal Studios, Florida, and saw either the old Ghostbusters Show or the new Disaster! attraction, you have seen this effect.

The Holograms that you have have seen on CNN during their election coverages (or the "Princess Leia" broadcast from a few years ago), are not holograms. The news anchor is looking at nothing. The image the viewer sees is a combination of 2 live scenes (the anchor and the reporter, or the anchor and the computer graphics), stitched together in 3D computer space, to LOOK LIKE the anchor is really interacting with graphics or a Holigram, but in reality he is interacting with nothing, and is on an empty stage by himself.
