Morning, all!

No essay this time - does anyone have any recommendations for introductory material covering common old school demo coding methods (e.g. bump maps, twisters, spinners, floating cubes, etc)?

I really thought YouTube would be piled high with this kind of thing but, seemingly, absolutely nothing to be had there. I don't really care if it's video, PDF, text files... I'm after something that explains the fundamental methods so I don't really care what platform / CPU it targets, either.

Cheers - BobW
