I always loved the look of older switchgear (as in power transmission, not network switches...). There are few examples given here, but some of the early gear genuinely wouldn't look out of place in a Frakenstein movie, like the original control room in at Battersea[1].

There is just something about a room covered in mechanical meters (not analog meters hooked up to a computer - literally mechanical computers hooked up with sense transformers to the high voltage lines) that read thousands of amps and 10s if not 100s of thousands of volts, often times with the megawatts of power traveling just on the other side of the panel!
