Imponderabilia, a performance by Marina Abramovic and Ulay, her then lover. This performance involved the lovers standing and facing each other while naked in a narrow doorway. This was the only doorway through to a part of the exhibition, forcing visitors to walk through the two artists with skin on skin contact if they wanted to get inside the space.
It is a poetic gesture, for if there were no artists, there would not be museums, and so the artists become the door into the museum. The purpose of the performance was then placed upon the visitors and their reactions, who became the protagonists of the performance with their raw reactions.
