Hologram

A hologram is an artificially projected being given physical substance through technological or supernatural means. It can also refer to messages or images that are given a three-dimensional physical form or the illusion of three dimensions on a flat surface. The most common examples of holograms used in fiction are the holodeck characters and The Doctor from the Star Trek franchise and the holographic communications used in the Star Wars franchise.
