yscript is a programming language based on propositional logic, designed for representing legal rules and building expert systems. The core logical dynamics of yscript programs are very simple, and the programs and their executions can therefore be straightforwardly visualized. This talk presents ideas for creating and interacting with yscript programs in visual terms.
