As someone who spent the last two years of his life helping people learn canvas: Love love love.

These are wonderful, and its especially wonderful that it's open source so others can learn from it. Even more so since there are so few good examples of animation(s) out there right now.

...On the other hand, demos/intros/effects that use a library that is explicitly made for just old-school demos/intros (http://code.google.com/p/codef/) are not as helpful to would-be canvas programmers and artists as it might be otherwise (if the demos/intros were made from scratch and stood alone).

I use chrome but this line reminds me of "This site best viewed in Netscape Navigator", which is a tad irksome :(
