That's a switch.

Our basement is in a bit of a state of undoing, because undoing always precedes doing, I guess. It is fully finished but we're making a few changes, including taking three bookshelves and trimming them out to appear to be built in to the wall (thank you, Terry Eklund...).

The big problem was the location of a light switch exactly where the bookshelves will go, so today's job was moving the switch. This was made much easier by the fact that the backside of the wall that holds the switch is also the inside of the furnace room and therefore unfinished.

All of this would take my fellow gunclubber Chuck fifteen minutes, although through inferior tools and generally shoddy workmanship, I managed to trim it down to forty five.
