RE: [photo-3d] Re holographic 3d

I think this is a sample of the what is being discussed...two opposing
concave mirrors...not holographic! even though we use that reference in the
copy.  http://store.yahoo.com/rainbowsymphony/mir3dopilgen.html

This sounds like the thing you can bu which consists of two concave mirrors
one with a hole in it placed facing each other. An object placed inside at
the focal point of the upper mirror is reflected through the hole by the
lower mirror to apear above the upper mirror. It does not have anything to
do with holography that I can see. P.J.Homer
