The balls in the Pod Sculpture appear to be rolling down the surface of the sculpture, which reminded me of the song "Like a Rolling Stone." The song talks about "Miss Lonely," who first chooses the easy path in life. But as she grows up and learns more about the world, her life gets tougher. Will she have enough life experience to handle these new challenges? The song made such an impact on the American (and global) audience that it in many ways changed the face of popular music.
