Concavo-Convesso, 1946. Bruno Munari
At the end of the 1940s Bruno Munari created a work-environment. In a dark and possibly ‘white cube’-style room, light radiated through a piece of industrial metal mesh, folded according to a mathematical precept: a work Munari entitled Concave-convex. The object, moved only by air currents or the touch of the visitor, created moiré patterns not only within itself but – most importantly for Munari – cast a complex, dynamic and mutable image onto the walls. The object was a two-dimensional square, curved in such a manner as to become three-dimensional, and expanded to infinity through the shadows that were thrown into the surrounding environment, suggesting the notion of the curvature of space. The obvious relationship of this object with the principles of non-Euclidean geometry did not lessen the atmosphere of mystery that permeated the environment, created by a skilful juxtaposition of form and structure, shadow and light.
