Just for the record  -  and to give credit where credit's due  -  this idea
was first formulated by UK Stereoscopic Society member John Gill as far
back as July 1994, in an article in 'The Stereoscopic Society Journal of
3-D Imaging, Number 125.    Some modifications, and improvements, were
subsequently suggested by Harry Everett in Journal 128 (April 1995).

Of course, neat but simple ideas like this can emerge quite independently
from a number of sources and there's no suggestion of any copyright.
