Tupac Hologram - Coachella 2012
Resurrected by way of a hi-tech 3D Tupac hologram that had taken months to develop, Tupac's return to the stage was the talk of the festival, with audience members tweeting their disbelief at how life-like the holographic protection was.
"I think I might have cried when I saw Tupac," wrote popstar Katy Perry, while Questlove of The Roots said, "That hologram haunted me in my sleep". Rihanna simply tweeted "#TupacBACK #unbelievable". The hologram was developed by AV Concepts, using holographic technology licensed from Musion, a British company that developed the technique and which retain a global patent on it.
