Square of the circle?

I went to see this part of a valley to picture what I thought was the theme today. I only read the first part of "Shape & Form in the Landscape: Curves and Circles". This is one of the last spots where the land consolidation didn't work (yet). The border between two pieces of farm land is not a straight line.
It looks curvy, no circles though. In reality, the curves are square angles, it's just the position of the photographer that causes the optical fraud.
