• Golden spiral: start with a rectangle whose length and breadth are in the golden ratio (about 1.618:1). Remove a square from it, and it leaves a smaller rectangle of the same shape. Repeat this process. You can then draw a logarithmic spiral called the "golden spiral". The centre of the spiral is sometimes called "the eye of God". [DC]
