The Atomic Number is an exhibition of abstract imagery by contemporary muralists and street artists, organized by Murals Inc. The Rotterdam artist NNamari contributed with a mural of 3x8 meters of an abstract black and white combination with clean lines and geometric shapes that were created and placed randomly, but within certain rules. NNamari was inspired by op art, geometry, architecture, digital art and post-graffiti. The work was on display in the Convex Architects building on Piekstraat in Rotterdam.
