The Wall Street Journal: How Tupac Was Brought Back to Life
It was the event of the weekend: Tupac, who died in 1996, was brought to life as a hologram and joined Dr. Dre and Snoop Dogg at Coachella Music Festival. Ethan Smith on The News Hub looks at the technology.

The technology used to project a lifelike, virtual Tupac Shakur Sunday night at Coachella has existed since the Victorian era, and at least one illusion designer believes the effect was even more remarkable in its original form.

When “scientific showman” John Henry Pepper first unveiled the trick in London in 1862, the audience saw a three-dimensional actor apparently floating on stage, according to Jim Steinmeyer, a top creator of illusions for magicians and other entertainers and also a historian of the craft.

More recent instances of the effect, known as Pepper’s Ghost, display a two-dimensional image with no “dimensionality.”

Steinmeyer states:

“If that sounds like it’s less impressive today, the answer is yes, it is.”
