The perfect monochrome is a surface without any marks: uniform, textureless, polished: a mirror.
“Nothing” turns into “anything”: the perfect monochrome throws the world back at the spectator.
The mirror only reflects what is already there.
It can show anything, but it cannot make a difference.
It says: x = x.
The only exception is the thing that cannot be duplicated: the subject.
The mirror returns the gaze of the observer. The subject becomes an object.
A mirror surface with a non-uniform orientation presents a multiplied, fragmented and/or distorted image of the world and the viewer. Automated cubism becomes a joke.
A closed optical loop between two or more mirrors multiplies an image ad infinitum.
Pistoletto’s “Metrocubo d’Infinito” implements the thought experiment: What if there is no input image?
