Also included in this Quadrum issue are a some really good reproductions of works by Victor Vasarely - a Hungarian-French artist, 1906-1997) accompanying an article by Henri Van Lier. Vasarely was a major figure in 20th century art. He pioneered a highly distinctive and idiosyncratic style of painting that creates an optical illusion of movement when observed (hence the term "op", I guess). Influenced by the Bauhaus artists such Mondrian and Malevich his paintings are minimalistic and geometric, often in pure black and white colours. Apart from the wikipedia entry, https://en.wikipedia.org/wiki/Victor_Vasarely I found this really good website dedicated to Op Art, http://www.op-art.co.uk/victor-vasarely/ and also his biography from the Tate Gallery in London: http://www.tate.org.uk/art/artists/victor-vasarely-2095
