Nature by itself does not have too many angles.  It has curves.  Humans have used the angle to create and have placed it everywhere.

The greatest cities in the world are replete with angles.  Most great architecture is composed of angles.  There is an element of the divine when you look up and the eye gazes into the heavens and follows the lines to infinity as the buildings rise above what we perceive as real.

Sometimes nature herself takes advantage of the angles we create to further their own view of life.

Sometimes nature even uses the littlest interstices created by angles to grow and develop.

Sometimes the angles we create are artistically beautiful in their own right.

Sometimes though, the angles depict the struggle of living in the city.

And sometimes angles show us life in a different time. Here is the Erie Canal that was built by the hands of laborers; each block assembled and placed precisely by manual labor.

In any event life can be organized and life can be chaotic and know that it can be anything you make it.
