Notes / Sevenfold
A note on the shape
A small radial study. Change the number of petals and the outline changes with it.
One rule, traced all the way around.
The recipe
Start with a circle. Let its radius rise and fall with the angle:
r = 96 + 30 × cos(nθ)
Trace it again at a smaller scale. The current sketch has 7 petals.
