My home studio doesn't have plain, unobstructed walls for some simple shots, and while a paper roll backdrop is a good substitute, sometimes you want a wall, or a corner, or you just want to use wallpaper.
So I built a massive construction with doubled-up cardboard sheet, girders made with pallet corners, these gigantic split pin things and hot glue, and then I spray-mounted wallpaper on it.
I also did it at the wrong time of year, when the air was still too damp and the heating needed to be on, so it didn't last an enormously long time before things rippled, because it turns out cardboard has some quite organic behaviours in moist air.
So it was almost a failure. But I'd absolutely do it again, replacing the cardboard with foamcore or thicker insulating board.
It was a really fascinating, liberating process to take that much control over the process, and I've been doing similar since, assembling my own photographic tools to a level that looks a bit like obsession.
I think maybe many software developers here don't understand the parallels between doing this sort of thing and assembling your "stack" for a few applications.
A true photographer's "tools" barely even start with the camera. There's a whole array of tools beyond that, beyond peripherals, that extend into the scene or into methodology.
