There's a lot of stuff hacked together in ways experts in the relevant fields would certainly not find beautiful. Expanding foam is probably not in the toolkit of very many master architects; most people have never read an electrical code (and in many places, there's no entity imposing one); many boats, snowmobiles, and other vehicles have been adapted in ways that would make the engineers who designed them want a drink or three.
Most of it works though, like that shell script you hacked together as a teenager from random mailing list archives to automate some task that still needs automating 15 years later. It works and it enables people to do things they could not otherwise do (the economics to support the relevant professional services wouldn't work). I see a beauty in that.
