Patrons walking down a long, narrow hallway suddenly see an actor running upside-down on the ceiling toward them.
Two story hallway with two large 45 degree mirrors at the end of the hallway will reflect the actor in the upper hallway (running toward the mirrors) will look to the patrons as if he is running toward them on the ceiling on the lower hallway.
- Cost of the two mirrors
- The timing of the actor is important. He needs to start running so as to reach the end of the hallway approximately when the patrons do for the best effect.
- The footsteps of the running actor in the upper hallway should enhance the effect if the acoustics of the hallways cooperate.
