Shadow theatre comes in two forms: Sbeik Thom (big puppets that are actually panels depicting certain characters from the story) and Sbeik Toot (small articulated puppets). The black leather puppets are held in front of a light source, either in front or behind a screen, creating a shadow or silhouette effect. Sbeik Thom is the more uniquely Cambodian, more formal of the two types, restricting itself to stories from the Reamker. The performance is accompanied by a pin peat orchestra and narration, and the puppeteers are silent, moving the panels with dance-like movements. Sbeik Toot has a far lighter feel, presenting popular stories of heroes, adventures, love and battles, with or without orchestra and with the puppeteers often doing the narration.
