The US presidential election has been a tremendous road show, full of twists, turns and drama, with big budget campaigns and big budget coverage. But there was one moment in the Presidential race that had the jaws of many technology-tragics dropping, and that was when CNN spoke to a reporter supposedly live via hologram. There she is, talking with the presenter, as a hologram, right in front of him.

CNN have subsequently gotten a wrap over the knuckles  as, in fact, the reporter was not seen by the presenter but only viewers by blue-screen technology.

The interesting fact is technology is available though. The fashion industry has used ground-breaking hologram technology, as this clip wonderfully demonstrates. How does it work? Will we see holograms pop up elsewhere? Will employers one day beam in interstate job applicants? Join us on Sunday night as our resident tech guru Gary Brown explains all!
