About the Octagon Grid design

Four octagon outlines fill the quarters of the square, and a small outlined square sits in the gap where they meet. Straight bars run from that square to the middle of each edge, where the slanted sides of neighboring octagons close on the frame in a sharp point. Short crossbars lace each octagon, breaking the white into small rectangles and wedges. In every corner a stubby L-shaped bar folds around a tiny square window.
