Project: Dot tracking game

I'm not going to start working on this project any time soon (too busy with other things), but it's a good graphics project for me to learn more about PyGame. I got the idea from watching the following video: Can Video Games Make You Smarter. At around the 2:45 mark, they did a demonstration of tracking colored dots on a screen. It seems like creating something that would mimic that would be not too conceptually but would certainly require me to learn a few more things about the PyGame language.
