Timing and Spacing are the most crucial thing in animation. They are what give the illusion of movement. Without the use of this we would not have any sort of animation to watch. In the early beginnings of animation they would use spacing and timing to create lifelike animations. They would use timing compared to the spacing so they would move and such. In the early days of animation they would space the pictures apart and use timing to make in much in a lifelike manner. Without this it would not look correct or even work in the first place. These two things are the very being of animation.
