This isn’t the title of any of Serra’s works or exhibitions, but the theme that runs through all of Serra’s work.
Serra uses traditional geometrical forms and models to produce unconventional shapes. They range from simple double ellipses to intricate and complex spirals and sections from toruses and spheres. They shift in unexpected ways and angles when the viewer walks around and through them, thereby giving him a dizzying, unforgettable sensation of space in motion. It is as if the space becomes the material Serra worked with and not the metal alone.
