Object to Be Destroyed is a work by American artist Man Ray, originally created in 1923. The work, destroyed in 1957, consisted of a metronome with a photograph of an eye attached to its swinging arm. It was remade in multiple copies in later years, and renamed Indestructible Object. It is considered a "readymade", following in the relatively new tradition established by Marcel Duchamp of employing ordinary manufactured objects that usually were modified very little, if at all, as works of art.
