As far as the book comment goes

I have actually been bugged about this by a few people, but at the moment barely have the time to write the tutorials let alone an actual book. I will eventually get to putting together a more book like format that contains the same content and a lot more like some small sample games at some point, but I need to finish up my summer classes here in the next four weeks and get moved in to my new apartment first

I have been toying around with the idea of the cafepress style printing so that I don't have to keep a bunch of copies around. That way if I update the tutorials/book pdf it can instantly be reflected in the printed/bound version that can be ordered from them. I will probably work out a pricing scheme so that reprints of the book for new updated versions are cheaper that the first copy, but I have a long way to go with writing before I start figuring things like pricing out. Thanks for the support on the idea though, it is definitely being considered.
