There’s a popular hologram by Walter Spierings that I think highlights what makes holograms unique: https://youtu.be/K-ahG_Q2xRc

It’s a microscope, that in the correct angle allows you to actually look down the viewfinder and see what the microscope was displaying.

This works because the hologram is recording the interference pattern of the photons that existed in the actual scene.

I’m really fascinated by these types of holograms and think they hold quite a bit of artistic potential.
