Maurer rose

Let r = sin(nθ) be a rose in the polar coordinate system, where n is a positive integer.

We then take 361 points on the rose: where d is a positive integer and the angles are in degrees, not radians.

A Maurer rose can be described as a closed route in the polar plane.

A walker starts a journey from the origin, (0, 0), and walks along a line to the point (sin(nd), d).

Then, in the second leg of the journey, the walker walks along a line to the next point, (sin(n·2d), 2d), and so on.
