Our mental image of balance is somewhat distorted because we tend to equate it with stillness - the calm repose of a yogi balancing on one leg, a state without apparent motion. To my mind, the more accurate examples of balance come from sports, such as when a basketball player spins around a defender, a running back bursts through the line of scrimmage, or a surfer catches a wave. All of these are extremely dynamic responses to rapidly changing environments. In the context of animation, directors have told me that they see their engagement when making a film as extremely active.
