Production company Kaleida made the hologram using a gauze it calls "Holonet." This contains real silver, which reflects projected light to create holographic effects.

Parts of the Holonet become transparent to give the impression of solid objects and real people existing in 3D space.

It combines this with motion tracking, SFX, VFX, and deepfake tech.

Kaleida's past clients include the World Wide Fund for Nature (WWF), Netflix, Nike, and Madam Tussauds.

The hologram told Kardashian West she is the "most amazing mother," praised her career, and said she married "the most, most, most, most genius man in the whole world, Kanye West."

"Sometimes I drop hints that I'm around, like when you hear someone make a big peefee, or when you make a big peefee," the hologram added, referring to the Armenian word for flatulence.

The hologram also danced and sang to Barry Mann's song "Who Put the Bomp."

Other celebrities who have previously appeared as holograms include Tupac Shakur, Amy Winehouse, and Michael Jackson. In 2017, Celine Dion performed "If I Can Dream" on American Idol alongside a hologram of Elvis Presley, and in 2018 the Ronald Reagan Presidential Library and Museum unveiled a hologram of the former president.

Robert Kardashian was a lawyer and businessman, best-known for serving as defense attorney during OJ Simpson's 1995 murder trial. He died in 2003.

Kardashian West, who turned 40 on October 21, shared the video on Twitter Thursday. She called the surprise "the most thoughtful gift of a lifetime," saying that it was "so lifelike."

She watched the hologram "over and over," adding that it made her emotional.
