We will literally unbox the principles of animation by exposing the individual frames of which an animated sequence consists. Everybody can join this workshop, including children and their parents. They will be provided with a template that serves as the basis for an animated sequence that is part of a longer animated film. The template is sufficiently open to spark imaginative new story elements or graphics. The result will be a short animated film that reflects the participatory approach of its production process, including different ideas and drawing styles, yet forms a coherent whole when tied together.
