Shadows are a basic phenomenon that can be created with any object or organism. In workshops I like to use recycled paper, sticks, string, tape and anything else that already casts an interesting shadow: twigs, leaves, yarn, hair, bodies.
The simplest light source these days, especially in a classroom environment is the good old overhead projector. Desk lamps or work lights can work too. For the most sophisticated outcome, halogen lights are the best (or xenon for those with larger budgets).
The screen can be a large sheet or cloth, cut and hung to the specifications of the shadow performers. A very good screen that I have been working with lately is butcher paper taped together to form any size from 4'x8' to 25'x50'. There are also expensive rear projection screens available.
The scripts for the shadow theatre performances are usually improvised, but in a disciplined and predictable manner. The stories can come from traditional fairy tales that everyone knows, or the workshop participants may make up their own.
