Holography as it is called, is the way of recording light that is scattered off of an object and being shown again to reveal an image as it already was seen, in the same position. This produces an effect that makes the projected/lit subject look 3-dimensional with depth. We've seen holograms presented in many films over the years. The main films in which we have seen holograms are the Star Wars films. In these films, the regular mode of communication between people is by way of hologram. The hologram is projected on a hand-sized pod and the two individuals are able to communicate and see each other clearly. But are holograms real? A supposed hologram was put into use during a clip in the news on CNN, but was it really a hologram? The answer is no, the supposed "hologram" wasn't a real hologram. What the viewers saw was only a projection that was layered onto the real-time interview tape. The people in the studio couldn't see the "hologram", but we could because it was slipped into the film. Although this was not a real hologram, there most likely are holograms in production somwhere. Maybe we will have holograms soon, who knows?CNN "Hologram":
