Surprising treasures in fresh viewpoints

I saw a castle rising out of the sea – or so I thought.
It was a photo that popped up on my computer screen:
a breathtaking shot of the southern coast of Australia. An
island sat in the middle of the water, waves lapping
gently against its rugged edges, and right
in the middle stood something that looked like
an old-world fortress, straight out of a fairy tale.
“How pretty,” I thought, clicking on the image
to enlarge it.
The fairy tale dissolved in a flash.
It wasn’t a castle at all. It was an oil rig.
