Tupac paved the way, and now Amy Winehouse may follow. British tabloid the Sun reports that the late Winehouse may go on a world tour as a 3D hologram. "The idea is in its early stages, but it’s hoped that Amy’s dad Mitch will maybe join her and do the introductions," says a source in the story. Billionaire Alki David is behind the plan, which would use the same technology that put Tupac Shakur on the stage at the Coachella Music Festival in 2012. That show so impressed David that he bought the rights to the technology. In fact, his film and hologram companies sued Cirque du Soleil and MGM Resorts this week for patent infringement over a hologram of Michael Jackson used in Vegas, reports the Hollywood Reporter.
