Why are the kind of holograms made by lasers not cool anymore? They’re just on credit cards and currency now. I always thought those were awesome. There used to be a hologram museum in Chicago when I was a kid. We went up there a few times and I always insisted on going.
The best ones were holograms of microscopes or telescopes and you could actually look through the eyepiece and see something through it!
The Kroger pharmacy here replaced their awesome pneumatic tube with a boring sliding drawer.
