Hi Olli,
i'm planning to do more examples in the future, each one targeted at a specific topic (like one example showing how to use MD2-files and animation, one for showing how to do your own texture-effects, one for blitting, how to write your own file-loader and so on...). But i'm kinda busy at the moment, so it may take some time for me to write them...
What topic are interested in the most?
