Bizarre Building

I went for a walk at lunchtime. I was passing Moorfields station when I came across an empty office building with a hole cut in it. The section that had been cut out of the front of the building was rotating in the hole.

I'd heard about this before, but hadn't been to see it for myself. It's very surreal. Pity it's going to be demolished and taken down next year.

Here's some info on the building/artwork from the BBC.
