1. A method comprising: displaying one at a time to a subject a sequence of object frame representations, each said object frame representation comprising an object in one stationary position of a plurality of predetermined sequential stationary positions; having said subject imitate said object representation in each said object frame representation; capturing images and data of said subject in real time while said subject is imitating said object in each said object frame representation; utilizing said captured images and data of said subject to generate, in real time, representations of said subject; displaying a composite overlay of one upon the other of each of said real time representations of said subject and said object frame representation in said stationary position until said subject approximates positional alignment with said object in said one stationary position; and displaying a next said object frame representation in said sequence of object frame representations when said subject approximates positional alignment with said object in said stationary position
