Dan Smalley's research lab at BYU is actively developing 3D volumetric holography technology.

The video is a bit old, but it has a few fun demos of the capabilities they've developed.

Strictly speaking that's not holography if I understood it correctly. Holography is based on interference created by a surface with a special pattern, and it doesn't require any matter other than the diffractive surface. Whereas here they say they move "particles" (what particles? dust? atoms?). Still pretty cool of course and a thing on its own.

I'm not sure if you can edit, but consider removing the ?is= parameter, to keep the link anonymous.

Seems fun but also no idea how that could be scaled or made to work in consumer products.

		It's "just" an engineering problem at that point though. It works. First it'll be at Disneyland for tens of millions of dollars and then it'll be in Vegas for millions of dollars and then eventually we'll be able to get it at BestBuy for $1,999 in 40 years.
