When I was a kid in the 90s my parents took me to some sort of art gallery hidden upstairs above other shops, that was doing a hologram exhibition (wavefront holograms, not specular ones like in this article). It was dark inside and they had a whole lot of amazing large format holograms of various things lit up. I kind of wonder why holograms of all types aren't more popular. It's still amazing to see a 3D image on a 2D plane that you can look at from different angles.

I spent ten minutes the other day trying to buy any laser hologram, and as far as I can tell the market just does not exist at all outside of "call us" pricing for science museums and such. Also doesn't help that the word "hologram" has been watered down to uselessness by competing technologies.

  Ten minutes! Wow. Did you check eBay? There are definitely examples for sale there. Holography-specific groups have hints on where to buy some too. The popular ones are hard to find, but you can make them yourself at home or find less sophisticated pieces for sale occasionally.

  Yep exactly, that's my experience as well. And I think the other reply saying it's possible to find them on eBay is kind of missing the point. Anywhere you can buy them is kind of obscure or unofficial. I don't understand why something so cool, that keeps working forever, is so relatively rare. I think the only other one I've seen in the wild since that exhibition in the 90s that wasn't some tiny thing, was a Lord Of The Rings one that Weta Workshop had given to a lecturer of mine.

This wasn’t in Chicago, perchance, was it? There was a lovely museum of holography there that I was lucky enough to visit in the early 2000’s before it closed. Your description reminds me of that.

  No, but that sounds like a place I would have enjoyed.
