Details: This striking optical work toys with the viewer’s perception, creating a subtle sense of motion through the use of staggered geometric forms. Evenly distributed vertical lines criss-cross with undulating horizontal lines. Vasarely fills in this grid-like formation accordingly to convey the impression of diamonds in varied sizes, all depicted in cool hues of light blue. In the lower right, he places a brown square over a portion of the composition; this square appears semi-transparent, altering the state of the geometric formations beneath it. When viewed for a few moments, the entire image appear appears as if slowly moving in and out, backwards and forwards. The viewer’s eye cannot pinpoint a specific “still” location but rather jumps around the composition, making this both a lively and engaging work. Created c. 1960, this unique original gouache is accompanied by a hand-signed Certificate of Authenticity from Michèle- Catherine Vasarely and is registered as catalogue no. 1109 in the Vasarely archives.
