Wall (400kg) made off concrete and paraffin. The shape of this sculpture is an isosceles triangular prism, that starts with cement (25 cm thick) and ends to paraffin (1cm thick). Due to the combination of these two materials the light from one side passes gradually to the other side. The artist attempted here to create a room without windows (10 square meters, approximately the size of a "white cell") in which one of the walls is not solid but fragile, barely transparent and unreliable in general for the enclosure of a person.
