1. Miyazaki says, "Our job as animators is not only to draw scenes. We must find the minimum necessary and important lines for the specific movement in a given action. The techniques of animation drawing are not the same as those of painting a still picture. Animation is a consequence of the audience's perception of movement created by sequential drawings. For this reason, each drawing in the sequence -- especially the lines -- should not be drawn too detailed; rather, they should be drawn less [detailed] and create an instant pause in the sequential movement.” (source)

    Sounds a lot like UI design to me.
