I came across this in my twilight surfings. I've seen Walt's notes around before, mostly here at Animation Meat but not in one nice compilation such as the one Leo Brodie has provided.
To take it a step further, I've made them all available for download with one simple click, all you have to do is save the PDF after you click here.
I can't wait to dig into this, hope you have fun reading and applying!
