Yves Klein, Leap Into the Void (1960) - A performance in which Klein leapt
from a wall into the 'void': in reality, Klein leapt onto a tarpaulin which was
removed later on. Klein used the photograph as evidence of his ability
to undertake unaided lunar travel
Charles Ray, Plank Piece I-II (1973) - Ray was part of a wave of artists during the 1970s who addressed sculpture as an activity rather than as an object. In this iconic two-part photographic work, the artist documents the use of his own body as the sculptural component through a complex balance between weight and gravity
Dan Graham with Harry Shunk and János Kender, Pier 18 (1971) - A performative piece
in which Graham photographed his surroundings by placing his camera on different
parts of his own body, working his way down from his head to his feet.
Erwin Wurm, One Minute Sculptures (ongoing) - A series of live performative works that
encourages audiences to engage briefly with their surroundings and to create
a sculpture using their own bodies and surrounding materials.
