What is a good way to go about creating motion files of people walking,
running, kneeling, sitting down, etc, etc?  I would like to record positions 
of hands, elbows, shoulders, waist, knees, ankles, etc, over time.

Are there some kind of really small intertial units that would be accurate
to .2" or so for a few seconds within a 100 sq. ft. area that wouldn't be
cost-prohibitive?

What else?  I thought of using bright dots a la the brute force Robert Abel 
and Associates approach for the commercial of the female robot for canned
corn, but the result's 2-D and require a lot more hand-work to use.
