alt Hacker NewsDan 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.

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

That’s not a hologram though.

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

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.
