My closest experience with holography was at a NYC Stereophile show years ago. The demo was in the David Wilson room and his source was the Basis Evolution turntable. He played a cut from an LP called "Bob and Ray throw a Stereo Spectacular" in which you can "see" the butler's footsteps scale up the stairs.
David Wilson was demonstrating the differences between 3d realism from analog and how its diminished thru redbook.
