I have now developed a habit of posting here nearly daily with new sketches and works that I do every day. This series deals with geometric shapes. Polygons have many corners: The most simple polygon is clearly the triangle, then the square, the pentagon, hexagon and so on. The most perfect polygon is the circle, since it has infinite corners or 'none at all'. However what interests me most in this work is the 3d version of the square: the cube.
