Constructivism

I saw these two construction workers at Utrecht Central Station, an important hub for the Netherlands' railway system, and watched them for a few minutes. The only thing they seemed to do was hammering nails into the wooden beam (the one on the left) and looking at the passing women people (the one on the right). After one side of the beam was finished they both started hammering and somehow it looked very primitive. I mean... this is the era of staplers, steel and concrete, right? I have to admit though, they were very skilled in the art of hammering.
