Leda and the Swan - László Moholy-Nagy, 1946
From the Tate Modern:
Moholy was keen to animate the position of the viewer. In the late 1930s, Moholy began to make sculptures out of bent Perspex. Often suspended from the ceiling, their gentle physical movement creates a dynamic viewing experience from continuously changing perspectives.
Ernst Scheidegger - Alberto Giacometti, ca. 1960
