No front or back at Yorkshire Sculpture Park

We spent an afternoon at the Yorkshire Sculpture Park. You should go! I liked this piece, called Shogun by Phillip King. As is often the case, it was the thinking behind it that pulled me in and got me thinking of Physics. He says that he has created no privileged viewpoint: it has no front or back. I was thinking that this is not unusual in Physics. It is unusual for there to be a particular direction in Physics, as with time only having one direction. However, I'd say that in Physics, having no privileged direction usually means symmetrical. This is not symmetrical at all.
