How to create a hologram illusion with Giant Mirror

In the stage version of the illusion, an actor is hidden in a recessed area below the stage and faces a mirror. The audience sees the actor’s ghostly image reflected in a sheet of glassless mirror suspended above the stage, and lighting can be used to make him or her appear or disappear.

Pepper’s ghost has been a popular theatre trick since the 1860s. In those days, an image reflected from a hidden, illuminated room appeared to be on stage, with the audience unaware they were essentially looking through a window. This “ghost” was at least genuinely three-dimensional, with the audience viewing a reflection of a live actor, who appeared three-dimensional just as your reflection in a mirror appears three-dimensional.
