The technology behind this is <a href="http://en.wikipedia.org/wiki/Musion_Eyeliner" rel="nofollow">http://en.wikipedia.org/wiki/Musion_Eyeliner</a> which uses the old Pepper's Ghost trick: <a href="http://en.wikipedia.org/wiki/Peppers_ghost" rel="nofollow">http://en.wikipedia.org/wiki/Peppers_ghost</a>
A bit more info - the tech behind this is a 2d variation on the Pepper's Ghost illusion ( <a href="http://en.wikipedia.org/wiki/Pepper%27s_ghost" rel="nofollow">http://en.wikipedia.org/wiki/Pepper%27s_ghost</a> ), apparently licensed from Musion (<a href="http://www.musion.co.uk/" rel="nofollow">http://www.musion.co.uk/</a>). It's had previous outings - animators at Square Zero have used it several times, including to recreate Frank Sinatra. <a href="http://www.squarezero.co.uk/what-we-do/holograms" rel="nofollow">http://www.squarezero.co.uk/what-we-do/holograms</a><p>It's interesting to see their videos from 2010, which are still quite realistic but look stilted compared to the Tupac projection.<p>And obviously these aren't really holograms. I'm not connected to this in any way, just looked it up earlier since none of the articles mentioned what was driving this.
Coachella has done a lot of innovative tricks this year. I was impressed that anyone in US could watch three of the stages live on YouTube. Live concert footage and other live videos on the web are going to quickly make TV feel overpriced.
I'm confused as to how they got him to say "Coachella". Had he performed there in his lifetime or did they have to create that word from old voice recordings?
Here are details on how they reproduced Sinatra, which is probably similar to how they reproduced Tupac:<p><a href="http://www.damonchernavsky.com/News_Archive/October_2009/Hologram_of_Frank_Sinatra/hologram_of_frank_sinatra.html" rel="nofollow">http://www.damonchernavsky.com/News_Archive/October_2009/Hol...</a>
Great question that was asked today was, "would you pay to see a dead artist perform in holographic form"?<p>Think about all the artists you could bring back and have perform for people when using this technology.
So after this is perfected, you could grab my image, make it look like I was the person who held up a bank and shot a hostage, and all the eyewitnesses would say it was me, and could give a positive ID? What would hidden security cameras show?
