hologram

A hologram (pronounced HOL-o-gram ) is a three-dimensional image, created with photographic projection. The term is taken from the Greek words holos (whole) and gramma (message). Unlike 3-D or virtual reality on a two-dimensional computer display, a hologram is a truly three-dimensional and free-standing image that does not simulate spatial depth or require a special viewing device. Theoretically, holograms could someday be transmitted electronically to a special display device in your home and business.

The theory of holography was developed by Dennis Gabor in 1947. The development of laser technology made holography possible.

That is NOT a hologram. That is a volumetric display. A hologram is a 2D object showing different images when viewed from different angles.

Lmao, yes it is. Seen Star Wars? Remember the scene with luke and R2-D2 projecting Princess Leia to Luke? Boom.

Matter of definition. For normal people who don't want to dive into volumetric display and light field technologies, there's no distinction. Although, I do think the definition requires an update. There's no theoretically about it. We've got the tech, even if it isn't quite mainstream yet.

Can theology or spiritual information be put on a hologram and be worn on jewelry?  Can emotions be changed or addressed by this method?
