🌀 Spherical Pendulum — Top-Down Rosette Trace (2D)

Top-down 2D view of a spherical pendulum's precessing rosette path, integrated from the real Lagrangian equations of motion in polar angle theta and azimuthal angle phi, with conserved angular momentum Lz tracked live.

⚙ Under the hood

Watch a spherical pendulum's bob trace a precessing rosette path from directly above, integrated from the real (theta, phi) Lagrangian equations of motion — not a simple back-and-forth planar swing. Adjust the starting angle, azimuthal kick, length and damping, and watch the conserved angular momentum Lz stay flat while the rosette slowly rotates.
