It would be VERY cool to do holographic 3D a-la the reconstruction room on "Bones" where they show what someone looked like in life when they have found a skeleton. Something like that shot with holographic cameras would be so cool viewed in the home.
I think you're right, the laser TV will have to do it for that effect. The current 3D technology relies on fooling the brain, so holograms would definitively be better. Maybe even as cool as the Holodeck on Start Trek!
