Spiral

This is plainly visible at Union Square, but I haven’t got a clue what it is or what it’s supposed to mean.

I’m told that it sometimes spouts smoke, but I saw no such thing.

Maybe you know what this is?

Maybe you can share?

In other news, I have no other news.

Not today.

Maybe tomorrow?

Probably not tomorrow.

But soon, I promise.  Soon.
