This weekend I just finished the first cut for the class game Pong. The Wumpus World example I made was well received and the 20 minute YouTube video very populate, http://www.youtube.com/watch?v=4CvjKqUOEzM. However I've since been asked for something a little simpler and smaller for a getting started example, so I thought I'd do Pong.

The initial cut was done with a single commit, so it's easy to see all the code in one place:

I'll follow up with a video soon, showing how it was made.
