regular geometric forms represent systematic thinking and the interrelationship between mathematics, optics, art and philosophy. anti is a geometrical form, a distorted cube, truncated on top and bottom to obtain rhombic and triangular faces. it reacts to the magnetic field of bodies, enabling an interaction with the visitor while its mechanism remains hidden. anti refuses instant recognition. its black, light-absorbent surface and monolith-like crystalline shape, that derives from albrecht dürer’s engraving melancholia i (1514), confronts the viewer, trying both to mask its form and to disguise its function and thereby absorbing information.
