Abstract: The shadow theatre is an unique performing arts, which utilizes a shadow as an main communication tool. This can be understood easily by an extension of traditional shadow play. Key difference comes from the fact that entire human bodies are used to make interesting shapes on screen during the play, whereas puppets or human hands are only used in the traditional one. Modern technologies on projection devices facilitate larger stage area, which enables the actors to use human motions in the play. Viewers often prefer full body shadow play over the traditional one because it gives energetic and delicate feelings simultaneously and it is less trivial to conjecture original performers' postures.
