For a certain ambitious artist, a large work in a public space is the test of their artistic chops.
An example of one such artist is Richard Serra, whose work changed how we view art in public spaces. Still, some of his works are claustrophobic (which is my problem, not his). And in one famous work, Tilted Arc, he miscalculated the public's reaction. He thought that he was making folks really see space - but he forgot that workers in a busy city feel a great ownership of the public spaces where they work. So he fucked up. (Ok he made a bad guess).
Still his works are intriguing.
And at least his heavy metal is appreciated as art.
Much less appreciated are the following monumental works of man and nature. They are mostly seen a hulks, and when they age, as eyesores. Still, I love them and love photographing them.
