I went for a run earlier this week and actually paused long enough to take some photos. These are the local tower cranes being used to build some new tower blocks (in an area where there are no tall buildings, so they'll stick out like a sore thumb, but anyway). When I see them at night, I mentally refer to them as the eyes of Sauron, because of the red lights on the top.
I took these pics because the light was pretty good. First pic I tried to get all the cranes in the frame and yeah, that worked, but it looks bland. Second pic doesn't really show the cranes properly, but the dramatic lighting works!
