Improving the 2D game engine

My quick guide on how to implement 2D sprite animation in Python/Pygame seems to be getting a steady stream of hits. For this reason, I am currently working on improving the quality of the guide and expanding my explanations.

I am also working on improving the engine itself. First, I want to remove the hard-coded pixel dimensions for the sprite frames and simply have the dimensions instead computed.

Secondly, I want to improve the quality of the sprites being used.

Lastly, I want to add some extra features such as basic collision detection.

Because I am busy with work, family, and school, you can probably expect to see the upgraded guide sometime around the end of December or early January.
