There's some good information in those books, but I don't think this one is redundant with them (admittedly, I've only skimmed it so far). Differences: 1) open-access; 2) interactive HTML5 demos of most of the concepts.
My opinion is that the killer project would be to combine them, which is to say put together interactive text/exercises around each concept so that you could read all the theory then see it in action.
