Flash Exercise: Anticipation and Overlapping

A quick exercise in Flash - we had to use a simple cube character with no legs so that the focus was on the animation movement. Before the character jumps he bends to anticipate the movement and then after jumping he bends further forward and then back again - this is know as overlapping.
The anticipation and overlapping are longer than the actual action of jumping as they are just as important to creating the illusion of movement as the jump is.
I really like exercises like this as I have always wanted to learn the fundamental principles of animation (and art) properly so i can employ them effectively. By learning how to utilize animation principles in simple exercises like this I can then employ them in more complex animations and in 3D work also.
