..what sort of odd distortion factors... does the "thing" just not appear smaller
or larger.. or does the actual proportions of the object appear to change.

How do you calculate the correct separation to give a correct phantogram ?

Also does the angle of attack (camera view) make a difference or need to be included 
in calculations ?

I'd certainly be interested in one... put my name on the list.

Could this technique be combined with lenticular screens or barriers to
produce an auto-phantogram ?
