3D Temple–Fay butterfly curve

3D particle system

The Temple–Fay butterfly is a famous polar curve: e^{sin θ} softens the body, cos 4θ cuts four lobes, and the fifth-power sine adds fine scallops.

Halves x ≥ 0 and x < 0 rotate about the body by ±α sin ωt, so the figure beats like a flying butterfly.
