This video is about two years old, but fascinating nonetheless.
Scotty Allen has a wonderful YouTube channel called Strange Parts that explores the back alley parts markets in places like Shenzhen, China, scrounging together the pieces to create, in this case, a working iPhone 6s.
This is not about creating a phone of your own. Rather, it’s a look at a remarkable parts market. Jump to about 4:03 and check out all those iPhone backs.
I’d wager that the parts market is even more varied and vibrant today. Kind of makes me want to hackintosh my own iPhone. Or, at least, replace the back with something unique and custom.
