During his studies at the Ulmer Art Academy with Max Bill, Josef Albers and Max Bense, from 1953-1958, Almir Mavignier created his first point-structure. The invention of this structural principal is based on color-points, which mark the interferences of fancied grids. Being set on canvas by using nailheads, the little pigment-pins add a relief-like character to the work. In accordance to specific rules they increase in size, so that a climax of light intensity and spatial effect emerges. In 2 quadrate [2 squares] two point-grids interfere in white resp. yellow with green and purple subpoints. The growing of the point’s scale, which can be hardly seen with the eye, causes a glow towards the center of the image. With his point-grid-images the Brazillian Mavignier became a protagonist of Op-Art as well as a leading member of the European artists groups ‘Zero’ and ‘Neue Tendenzen’ (‘New Tendencies’).
