Easier to take in scale of size when you have holograms? I imagine it would cause the same percentage increase in learning the books have been proven to provide over computers. It keeps your attention focused better.

And Yu-Gi-Oh touraments. Eventually, most of our daily lives will involve holograms but first it has to be used for a child's card game

If holograms like this can be generated in real-time via an array of cameras, I can see them making a swell cloaking device. That's one application.

my dad was doing holography in art school during the 70's

Well MY dad is a firefighter AND goes to space on the weekends!

I obviously dont have the first clue about what holography really is.

for you.
