At first glance, this might be a photo of the front of a 12-story building. Even the “sky” area looks pretty sky-like.
It’s actually a close up photo of a ventilation grate. I didn’t intend to make it look like a building, in fact, I shot this photo without looking thru the viewfinder at all. I just extended my arm down to the grate and snapped it. This grate is along the floor of a light rail car…and you know you don’t want to touch the floor of a light rail car with anything other than the bottom of your shoes.
