I think the ads are a small price to pay to get a detailed tutorial like this one. Granted, it would be nice to see
things like this in an easily copiable/downloadable format,but for sites that don't get some kind of
charitable/corporate funding I don't mind looking at some ads as long as they're not popups.

It is surprising to me that there isn't more open source game development. Maybe one day after I have learned a
lot more, I'll take a crack at it...
