The web is abuzz this week with the recent and shocking appearance of Tupac Shakur at the Coachella music festival. The masterminds behind the posthumous resurrection used the most modern innovations in technology to create the hologram, right? Wrong!
In fact, Tupac’s hologram is based on an illusion first described in the 16th century, and popularized in 1850′s London by Professor John Henry Pepper. Using a chamber under the stage, proper lighting and a projected image through an angled pane of glass, the Tupac’s likeness was brought to three-dimensional life. It’s still an awe-inspiring and exciting illusion, but not exactly the cutting-edge of scientific innovation!
