Cast iron on the wall or ceiling?

An idea that sounds weird at first, but hold up, take a look at these lights, it is just my personal opinion but they do look original at least. A cast iron wheel mounted on the ceiling or a wall, nice wire and an Edison light bulb make this design an unique combination of industrial hardware and modern, loft like item.

Some of these cast iron blocks and wheels are not easy to find and not very cheap to buy. But it is worth the effort, the final effect can literally bring some new light into the room.
