I'm not finding a lot of details about this, but holy smokes: Enzo Mari playground!
Created in 1968 in Carrara for an exhibition of stone design. A newly constructed maquette circulates for years beginning in 2000, part of Aires de Jeux, a French exhibition of artist-driven playground design.
Travertine monoliths around a slate court, which evokes the imagination-stimulating, small-town piazza where Mari and Stanley Kubrick played together as children.
