Re: an ersatz-3D image
Good question, so a vote from me.
However, Hitachi has such a system, demonstrated it at CEATEC around the middle of the last decade.
It requires multiple cameras around the space to capture the video, and the playback system is electro-mechanical, delivers much the same effect as the hologram viewers in THX1138, or Princess Leia in Star Wars.
Unlike holograms, you can walk around the playback system, and it doesn't have the same problems with colour distortion. One of the demos was a sumo match.
I thought at the time (and still do) that it was very ingenious, expected to see the system pop up in public spaces, but the costs of commercialisation seem to have been judged to be too high.
Respect for NDAs precludes more, but we are now restricted to 'jump out of the screen' 3-D, I like my 3DS, but have not seen any of the recent American blockbusters in 3-D.
I like the old ones, using it as a shock effect, for that, my prize goes to Paul Morissey for 'Blood for Dracula'. Flesh for Frankenstein, Jaws 3 in 3-D, all fun.
