Creepy, 3D versions of Gorillaz performed live when they won best artist at the MTV Europe awards in Lisbon on November 3rd.
The Times of London reports that the illusion was achieved using an old Victorian parlour trick known as “Pepper’s Ghost”:
To make Pepper’s Ghost appear, someone offstage would be highlighted so that the light waves bounced off a piece of glass, strategically placed at an angle. The reflected image would appear to be onstage. It is the same principle used in fighter aircraft, where a ghostly image of graphic flight and radar data float before the pilot.
