This book is excellent. Used it for my animation class. Although, my instructor went out of order for the book, what he said was repeated throughout the book. I also love how it explains the history of animation as well. If you ever get a chance, pick up this book. I do have to say, that while trying to do the animation from the CD, it does get confusing with the directions. The directions should have been a little more step by step. Other than that, its a pretty good learning tool.
