1. A method of simulating relative motion of objects in computer animation comprising the steps of: providing a motion of a kinematic object, where the kinematic object is an element of a computer animation display; providing at least one dynamic object associated with said kinematic object, where said at least one dynamic object is another element of the computer animation display and where motions of said at least one dynamic object are based on the motion of the kinematic object; selectively manipulating the motions of said at least one dynamic object to simulate physical motion; and displaying the elements of the computer animation display, including associated motions of said elements.
