 An ageless throne is situated in a room. A sword tied with an invisible thread to the ceiling is hanging down, just over the throne. The shadow of the sword and the throne drops on the opposite wall, so that a person sitting on the throne can face them directly. However, the shadow of the sword alone is an illusion, as a beamer is projecting an animation of the sword on the wall. So, when someone sits on the throne, the sensors hidden on the seat and the back activate the animation and the shadow-Damocles sword swishes down.
