Take a look at this
on-stage holographic video conference PR show run by Cisco's CEO John Chambers. They have100 systems installed at Cisco , he says, and this on-stage PR show makes you even think Cisco would be the mastermind behind this technology. But the credit for it goes to the UK company
Musion Systems LTD. Musion holds the intellectual property for holographic video and licenses it through a comprehensive list of resellers across the world. What Cisco did is not unique, though. as there are plenty of other large companies doing the same "trick" as you can see in the Musion portfolio website too. Virgin's Richard Branson is of course the ideal person to do such a virtual show, being "beamed in" from his Caribbean island to a London digital megastore opening event. To top things, you can also let people come back to "life" again and have them appear in a live concert. Done so in Japan:
"The untimely death of charismatic guitarist Hide in 1998 not only put any such plans on hold but sent Japan's leading rock band into hiatus for ten years. Hide was "brought back to life" at Tokyo Dome in March 2008 using Musion Eyeliner Holographic Projection System."
