I have to laugh, considering

Salvador Dalí’s first three-dimensional hologram was First Cylindric Crono-Hologram. Portrait of Alice Cooper’s Brain, which he created in 1973:
Subject
The hologram depicts Alice Cooper wearing jewelry worth around $2 million, including a tiara and necklace. He sits cross-legged on a rotating base, holding a statuette of the Venus De Milo as if it were a microphone.
Background
Behind Cooper is a Dali sculpture of his brain covered in ants, a trademark of Dalí’s.
Exhibition
Dalí exhibited the hologram at the Hotel Meurice in Paris, France on May 23, 1973.
Dalí was one of the first artists to pioneer the field of holography. He worked with Lissack, an early pioneer in the use of holography for commercial products. Creating and displaying holographics in the 1970s was challenging because of the bulky and expensive equipment required, such as lasers, mercury-arc lamps, and halogen lights

Thank you for that. I'm sure the current level of holographic design is VASTLY superior to Dali's portrait of, of all things, Alice Cooper's brain in 1973! :)

There's been much frenzied talk in the media about how our fleets of "drones" don't show up on radar, or have a heat signature, or disappear if light is shown on them. If they're holograms, that would seem to be quite logical!
