Shadow plays using marionettes are performed in many countries, but Indonesia's Wayang Kulit is one of the best known examples. Plays are enacted by putting a light source behind the puppets to cast their shadows on a screen. The plays serve a religious function and are performed at festivals and weddings. Wayang Kulit has been designated as an Intangible Cultural Heritage in 2009. Even today, its stories based on Hindu epics and their world of legends remain alive in the minds and hearts of the spectators.
