Camera Obscura del Arky

[P3D <ocanna@xxxxxxxxxxxxxxxxxx>]

A couple of years ago while in Hot Springs, Arkansas I visited the
technology type museum called (I believe) the "Mid-America Museum"
or something like that.  One of the exibits was a camera obscura.

It was nicely done.  The "pinhole" looked like a wide field copier
lens with an aperture of about 3.5".  The "film plane" was a curved
white wall and seemed to work quite well.

Now if one constructed a similar room and used TWO lenses with 
polarizers to project overlapping immages on to a silver screen 
could one hang like a bat and view a gigantic 3-d landscape?  I've
not been following this thread closely.  Has anyone else suggested
such a thing or is it just me?
