At the Yellow Ball Workshop, children and teenagers make animated films using simple art materials and camera equipment. Based on the animation techniques developed at the workshop, complete instructions for constructing backgrounds and characters and for animating the figures are provided. Setting up and using the camera, splicing film, synchronizing sound and picture, and the use of special effects and movie techniques like fading and panning are explained. Scenes from workshop films and photographs of participants illustrate the procedures. (JK)
