On Friday Alec showed us videos by Jesse Baumgartner which shows the development of follow through and overlapping action.
The process starts with key poses which gives a foundation for the in between poses. In these series of video the change of the animation is gradual. The hand motions of the spy with the action of the coffee cup and the hand motion afterwards are carried and create a momentum. These follow through and in addition with the head turns creates an overlapping action.
