Controversial Works of Art: Rhythm O

Serbian performance artist Marina Abramovic has guts and a lot of faith in humanity. In her 1974 installation, she used herself as a subject. Laying out 72 objects in front of her, she allowed the audience to do whatever they wanted to her body. There were nails, knives, flowers, perfume, and even a loaded gun. For six hours, the initially gentle audience used the tools in harsher and harsher ways—one even aimed the gun at her head.
