Shameless self promotion:
I have a Youtube channel where I do WebGL screencasts, as well as a myriad of other topics. Currently up to 99 WebGL episodes, and 21 3D Math episodes.
They're a lot more low level, and if you start at the beginning, you get to really understand each piece as it builds up over time. I find that a lot of topics and books rely on the user/reader to check out the source code to grok what's going on (which, often times, needs to be the case because the topic is advanced already, and has a level of expectation that the user will do their homework). That said, it's been nice building up over time because it's easy to see where things come from.

Just kidding, but I feel like I need to donate something to you, for all of this; where can I do that?
