Scaled rosette curves with 12-fold symmetry centered on antipodes of a sphere. "Scaled" refers specifically to ordinary scaling in the equatorial plane followed by "stereographic projection" from one antipode, and illustrates a velocity field that at each point is orthogonal to, but of the same magnitude as, the velocity field of rotation about the axis through the antipodes.
