The goal behind this exercise was to practice nesting movie clips in order to create a dynamic animation. The movie clip on the root timeline is the pelvis. The pelvis in turn contains movie clips for each of the legs and the torso. Each leg contains the lower leg, and each lower leg contains a shoe. The torso contains both upper arms, and both upper arms contain forearms. Each forearm contains a hand, and all motion tweening is based on prime numbers, so that the likelyhood of any movie clips landing in a repetitive cycle is as slim as possible.
