Abstract

Rewriting systems are popular in end-user programming because complex behavior can be described with few or no abstractions or variables. However, rewriting systems have been limited to manipulating non-rotatable objects on a grid, such as in Agentsheets or Stagecast Creator. Systems that allow free-form movement of objects must use other techniques, such as the sequential programming by demonstration in Squeak. Viscuit is a new rewriting system that introduces fuzzy rewriting, which allows freely positioned and rotated objects to interact using only rewriting rules. The result is a system that allows users to specify animations in a highly interactive way, without textual language or menu selections.
