That video just made my day - awesome! Can't wait to get the book. I also realised when browsing the Amazon page that the author is the same guy who wrote 'casting spels' (http://www.lisperati.com/casting.html) which was also great.
If your reading this Conrad do you mind me asking you about your art work? It's, hands down, some of the best cartoon drawing I've seen on the web. I'd love to know what tools you use to do the drawing and make the animations, and what process you go through when developing them.
