I always thought that body art goes with a beautiful naked female body, but these pictures prove that I was wrong. These images are beautiful and there is no nudity. ;)
More extreme body art can involve things such as mutilation or pushing the body to its physical limits. For example, one of Marina Abramović's works involved dancing until she collapsed from exhaustion, while one of Dennis Oppenheim's better-known works saw him lying in the sunlight with a book on his chest, until his skin, excluding that covered by the book, was badly sunburned. It can even consist of the arrangement and dissection of preserved bodies in an artistic fashion, as in the case of the plastinated bodies used in the travelling Body Worlds exhibit.
Body art is also a sub-category of performance art, in which artists use or abuse their own body to make their particular statements.
