Quick reply about holography...
Research into holographic displays has produced devices which are able to create a light field identical to that which would emanate from the original scene, with both horizontal and vertical parallax across a large range of viewing angles. The effect is similar to looking through a window at the scene being reproduced; this may make Computer-Generated Holography the most convincing of the 3D display technologies, but as yet the large amounts of calculation required to generate a detailed hologram largely prevent its application outside of the laboratory. Some companies do produce holographic imaging equipment commercially.
