We're not even altogether sure how we stumbled onto this, but we love this one-of-a-kind lamp for lighting artwork. It's made of brass and turned on something called a mini lathe...
Apparently this mini-lathe owner made the lamp himself for a painting in his home. Fine job, if we do say so ourselves. We love the solid metal cylinder and simple articulating arm.
This is not at all the same, but it's an off-the-shelf art lamp that has the same delicate scale of the custom one up top. Find it at Lightology:
