• AnimationDirection->Forward specifies that the animation should run through successive selected graphics cells in the order that they appear in the notebook, and should then start again at the first cell.
• AnimationDirection->Backward specifies that the reverse order should be used.
• AnimationDirection->ForwardBackward specifies that the animation should run from the first cell to the last, and should then reverse back to the first cell again.
