Here is a skeleton for Tic Tac Toe. It is far from complete, but illustrates subclassing the widget, and handling keyboard presses, and adding children to app.App.

If you have any questions on any part, just post them in the comments below and I'll try to answer them.

Anyone want to take a crack at finishing this game??
