This BMW i3 Factory Tour is pretty incredible. It's full of glorious automation and a few tools I never thought I'd see in a factory setting. It is long, though, so I made a list of highlights.
Overall, the microscope we use at work is fantastic, although photographing what you see through the eyepieces is extremely challenging without an attached camera. Removing the main viewing assembly was the best way to decide if we could build an adapter ourselves, but it also revealed these glorious barrel cams.
