Those small metal rods are remarkably disorienting. That is likely a good thing when you are making imagery/meaning out of the National Socialist past.
This image has a lot to look at. I was first drawn to the gaping whole in the ground, wondering exactly what it was that I was looking at. Next I noticed the people caught in action, working at this construction site. One can tell that it is a considerable undertaking, but it is not obvious (at least not to me) what exactly is being undertaken.
