About the Three Node Web design

Five matching rings sit on the sheet, each a fat circle of steel around a round opening, and only the middle ring carries three bars at once. Those bars run to the upper left, to the upper right, and down to a fourth ring that passes a single bar along to a fifth, so the chain drifts from one corner toward the other. Every bar is shorter than a ring is wide, and no two meet at the same angle.
