To illustrate most of the exercise text in this book, I have used the simplest of simple illustrative characters-Arnie-to demonstrate the essence of what is being said. Arnie has been with me on my animation and teaching journey for a long time now. He is so easy to understand and draw that I find he’s a huge asset for student animators especially. Animation beginners are often overwhelmed by the complexity of the principles of movement they need to knowlet alone drawing a character that represents them. So by offering such a simple teaching form to them, it makes everything else they are attempting to learn and demonstrate so much easier.
