Vito Acconci (1940 – 2017) was an influential American performance, video and installation artist, whose diverse practice eventually included sculpture, architectural design, and landscape design. His foundational performance and video art was characterized by "existential unease," exhibitionism, discomfort, transgression and provocation, as well as wit and audacity, and often involved crossing boundaries such as public–private, consensual–nonconsensual, and real world–art world.
