The GUI will respond to the user changing selection, and when the user interacts with the GUI, it will update the Maya scene. This project will teach us the fundamental concepts that allow the decoupling of Maya and PySide components. This decoupling allows an ever-more-complex set of interactions while still keeping the code maintainable.
