7. Arcs
8. Secondary Action
9. Timing
10. Exaggeration
11. Solid Drawing
12. Appeal

Using simple shapes (square, sphere, triangle) create your OWN demonstration that utilizes 2 or 3 of the principles of animation.
Be sure there is a TITLE in one of your flash layers that indicates the principles that you are illustrating, and be sure that your name appears on the stage as well.
The duration of the animation is up to you, but it should be 800x450 pixel resolution, and should be paced so that it is appealing to the viewer.
