My guess is that it's because there are only so many ways to arrange cases of bones and reproductions of skeletons in a way that's visually interesting, compelling, and informational.
It's a small enough industry with expensive enough parts. There's probably exactly one and a half companies that make cases for uses like this that provide the furnishings for every natural History museum.
Oh, that makes all the sense in the world. You're probably right.
Even if it's a dozen companies making cases for every type of museum, zoo, and aquarium, it's probably going to be a little bit like Chromebooks where the vast majority of different options are going to look the same unless you stare at them right next to one another or are in the industry. Most industrial design ends up pretty samey because that's what people expect.
I took this picture myself. Far as the owner he has video playing about what they do and they literally clean the bones for the museum, which includes;
He also said that when he dies he wants his body cleaned and his bones put on display. The place is neat. They use bugs that eat the dead flesh off the skin. If you are ever in Oklahoma City definitely g check the place out.
In times of satisfying pet lives, though it’s quite different than “golden retriever owned by upper-middle class American family”, this has also got to be right near the top of the list.
