Force Projection

Force Projection is a mysterious and rare Jedi ability. It is a technique with which a Jedi creates an inanimate apparition similar of himself, used to distract, confuse or lure enemies.

It is maybe related to the Jedi mind trick, or the trick that [Obi-Wan]] used to past the guards on the Death star I (although this had to do with a 'sound' and not an apparition).
