Rose curve defined by the sinusoïde r = cos(kθ) in which the angular frequency k = n/d. Naturally, the pattern diagonally remains consistent, as n/k=1. Spirograph but then mathematical.

Rose curve, white on black, A3

• In this plot, n runs horizontally from 1 to 23, and k vertically from 1 to 16.
• So 368 roses
• 40 x 27 cm

Rose curve, black on white, A3

• 10×10 grid
• From n/k=1/2 to n/k=10/10 and everything in between
• 27 x 27 cm
