so how can we see this technology be used in the future? I know people can buy holograms for their homes but what other ways can this technology be used as a consumer product? The video hologram he was showing at the end makes me believe this could be used somehow for the future.

Technically, 12 nanoseconds wouldn't be an "infinitely short period of time". It's only a 12 nanoseconds short period of time! =P

OK, so I see that a hologram uses an interference pattern somehow, but how does that same interference pattern allow light to be reflected in such a way as to produce the original image? I know that with ordinary film, the surface reacts to the intensity of incoming light (getting darker the more light there is--and hence what you get is a negative), but how do you get a piece of film to reflect directionally asymmetric light? Is there something special about holographic film that allows this?

Holograms can be done

Excellent explanation...clear voice and instructions. Thank you...

Ah! I looked straight at the green laser. I'm blind! That is cool.

I think computers in the future will be hologram 3d technology like in the movie The Time Machine (2002) when the guy pops up in a glass frame giving guy peirce information online etc.
