Gyroscopic Precession — 2D Rigid-Body Lab

This 2D companion drives the same rigid-body precession physics as the 3D gyroscope through a plain canvas view built for reading the numbers rather than orbiting a scene: independent sliders for spin rate, moment of inertia, mass, pivot-to-centre-of-mass distance and tilt angle feed L=Iω and τ=mgr sinθ directly into the steady-precession formula Ω=τ/(Iω sinθ), rendered as an oblique side-view cone trace, a true top-down orbit, and a live Ω-vs-ω curve — so the counter-intuitive result that a faster spin produces slower precession is something you can watch happen, not just read about.
