Untitled, plate 2 from Spirale Blanche

John Armleder has been a driving force in Switzerland’s contemporary art scene since the 1970s. Here he pays homage to Marcel Duchamp, a hero of modern art who in 1935 introduced his Rotoreliefs, which were spinning disks that produced optical illusions of depth or three-dimensionality.In Spirale Blanche Armleder follows Duchamp's lead and coveys an illusion of depth by overprinting his lithographs using two or more colors, shifting them just enough to create the sensation of dimensional relief. Surprisingly, on close inspection, many of the prints are not actually abstract designs, but reveal arrangements of fish printed in dazzling arrays of color.
