Impressive, but mainly for noobs.
I found the claymation bit fairly informative, not having done that stuff before and not having made much of an effort to learn how.
Well, maybe when I have money spare for a web-cam I'll give it a shot. I don't fancy using my digital camera and having to set up a batch process to resize/resave all the pictures before having to spread them across the timeline. Actually, now I think about it, it's still not much work compared to fbf...
Anyway, some bits of code seemed useful and the NG-specific bit was a nice tribute.
However, your buttons were a bit horrible with the hit-box, making me lose a bit of faith in your teachings and it would have been nice if you'd actually tried to explain the AS a bit more fully.
You should really specify version numbers more clearly for the programs. And whilst you do cover a lot of material, most of it hasn't got as much depth as I'd like.
It remains, however, useful to any relative newcomers. And for a free resource, supplied the way it is (as a flash file), it seems to stand head and shoulders above its peers.
