Long loved Russian Constructivism period, I visited an exhibition "Defining Constructivism - Rodchenko and Popova" at Tate Modern.
"Russia has given birth to its own art and its name is non-objectivity" Rodchenko [1918]
"The line has revolutionized our view of pictorial surface by changing an idea that form is no more than a patch of color" Rodchenko [1921]
"I don't think that non-objective form is a final form; it is a revolutionary condition of form" Popova [1921]
"The line becomes an independent graphic element as well as a border of form or its continuation of space" Popova [1923]
