The reason this site is not very active is that we have been learning a shitload of stuff all at the same time. Here's an animation I started working on weeks ago. I've finally turned him into an anigif.
He is an example of inbetweening between keyframes. The top of the leap is a keyframe, as is the very other end of the action. There is a small hold on the first frame in an attempt to give some anticipation to the leap. There is also a "moving hold" - something that David mentioned Disney developed. If it's good enough for Disney it's way good enough for me!
