Moholy-Nagy saw himself less as a painter than an experimenter, using canvas and paint to examine the phenomenon of light as an elementary pictorial medium and formative principle. »Constructive Art« according to the artist, who was fascinated by technology, »extends to industry and architecture, to objects and relations, constructivism is the socialism of seeing.« Q XXV seems like the product of an examination on the play of light with a moving, three-dimensional form and resulting spatial interrelation. »Painting is the proof that paint has its own effective existence apart from its material tangibility. The surface becomes part of the atmosphere, the atmospheric base in sucking up the external of its existing appearance of light.« (László Moholy-Nagy, 1929)
