Transcript

We're looking for the, the math for the graphic design for the for the next ICM, there were tried many ideas, and I was personally very inspired by the work of El Lissitzky with his three-dimensional object, curved object. A lot of interesting geometry. But what eventually was selected is more inspired by Kazimir Malevich and his very simple shapes... Read More
