Angela Bulloch’s geometrical sculptures consist of several assembled figures known as polyhedra. Conceived and designed within a digital imaging program, each module appears distinct, whilst at the same time relating to the others. Made of either untreated or oiled MDF, Corian (a composite material), or powder-coated steel — which allows them to be installed outside.

Bulloch’s variety of mediums has an ability to provide surfaces that are optically difficult to grasp. Several sides of each modular element have been painted, alternating light, bright or dark colors. This coloring increases the optical illusions of pushing and pulling planes: at times the sculpture seems graphic, seemingly shifting between two and three dimensions. The appearance of each column changes according to one’s point of view. From one side the irregular aspect dominates, whilst from another the impression of a certain totemic regularity prevails.
