I think that this book should be considered a "must own" for anyone serious about learning how to articulate a 3D character's face. This book goes into extreme details not so much on the tools but on the concepts, or theory, around how to move points in a CG face properly. I can't stress enough how eye opening this resource will be for students of this craft. If you want to create a 3D character and animate it, you NEED this book.
