Due out next month Don Hahn’s forthcoming book The Alchemy of Animation: Making an Animated Film in the Modern Age now has a video teaser for it up at YouTube. Get a taste for the book by hearing (and watching) Don discuss the three principle types of animation: hand-drawn, stop motion, and computer-generated. (Viewing tip: look for the “watch in high quality” immediately below the YouTube screen to watch the trailer in a much clearer resolution.)
