This demo illustrates the simplest way (that Andy could think of) to build a PureMVC application in python using wxPython as the GUI. A string in the model is displayed in the GUI in a textfield. Anything you type gets converted to uppercase and stored back in the model, courtesy of a command class triggered when you hit the ENTER key in the GUI.
