As I'm a Syracuse alumnus, my Orange coverplate:
A real antique power outlet. Combination tandem and parallel slots. The parallel slots accept modern non-polarized line cords. The tandem slots would accept a 250V 15A plug if you removed its ground prong. I even found a Hubble tandem plug without ground of post-war vintage that fits. Appears that back in the early days of electricity, there were two different kinds of 120VAC plugs, parallel and tandem. And this outlet was made to support both. No UL seal of approval on the antique power outlet, UL may not have existed a hundred + years ago. A more modern tandem/parallel outlet is also pictured, alongside the antique and a modern NEMA 6-15 250V 15A outlet. The tandem plug will fit the NEMA 6-15 outlet, but if the tandem plug feeds a 120V load, the load will blow up!
Here I modified an old Despard uniline deco outlet cover to fit a Decora device, here a duplex ethernet jack. Only reason for the orange and blue jacks is that it's my college's school colors, Syracuse Universuty. Of course almost nobody will make the "connection".

Installed a GFCI outlet in the bathroom of my mom's house. "What's unusual about that?" you ask. Well I was able to mount it so the cover plate was flush with the tile on the wall. So it looks like another tile except for the different color. The cover was nearly the right size to fit between the existing tiles vertically. I had to file the cover a little for a better fit. This outlet is between the sink and an old fashioned 1950's era wall mount metal clothes hamper. Yes, the bathroom dates from then, that's why the funky tile color. The tile to the right was a salvaged scrap from previous bathroom maintenance, the ragged breaks hidden by the hamper trim. The electrical box was mounted to the sheetrock behind the tile using those F shaped metal things. Also a few screws to the sheetrock, though I don't expect those to do that much. For added support I added a block of wood about 2 inches thick to fit between the box and the wall stud the hamper mounts to. Cut to fit. Removed the hamper to install a screw thru the stud to attach the block of wood to the stud. And with some carpenter's glue as well. And in turn the electrical box has screws to mount it firmly to the block. You can see this block to the right of the box in the picture. That way the wall won't flex as one plugs and unplugs hair dryers and such. Lightly grout the cover plate though, you need to be able to remove it to gain access to the electrical box as per NEC code.

An insulator: Found it on the ground 50 years ago just after they installed new lines.
And a ceramic one from the same era the linesmen just gave me. It has a logo: an outline of Illinois with an "I" in the middle.
