Description: This thesis presents a sketch-based system for authoring 2D animations. We propose an interface that combines fluidity with a high degree of functionality. The interface eschews implicit gestural input and is instead menu driven off a single closed stroke (squiggle) and streamlined for fluid sketching. We explore a design philosophy where a dynamic hierarchy of motion clips is built over an unstructured set of objects opposed to the common practice of defining unstructured animation curves for a static hierarchy of objects. Clips define motion within the timeframe of their parent and present an alternative for capturing hierarchical motion. The evident lack of an object hierarchy for articulated characters is addressed successfully using deformable object connectors. The system supports both keyframe and performance based animation of objects and motion clips allowing animation to be rapidly specified through a stylus input device, and further refined through keyframing.
