Tupac performs at Coachella ... sort of

Audiences were treated with a reunion between deceased rapper Tupac Shakur, Dr. Dre and Snoop Lion (formerly Snoop Dogg) at the 2012 Coachella Valley Music & Arts Festival in Indio, Calif. The question on most people's minds was, "How did they do it?"

Although the perception was of a 3D likeness of Shakur, the image was actually a 2D image. Shakur's likeness was projected onto an angled piece of glass on ground, which in turn projected the image onto a Mylar screen on stage.
