About the Spun Squares design

Thin square outlines turn a few degrees at a time as they shrink inward, so their corners trace a spiral that winds toward the middle. The largest frames overlap at the rim and leave a ragged ring of points around the edge, with one square sitting upright among the tilted ones. At the center the lines give way to a small solid black square, pierced by a single round hole, like the bottom of a tunnel drawn in outline.
