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
