🌀 Frame Dragging - 2D Equatorial Map of Lense-Thirring Precession

2D companion of the 3D frame-dragging simulation: top-down equatorial map of a spinning neutron star with swirl arrows, an orbiting gyroscope, the 1/r^3 falloff plot and numerical checks against the closed-form precession and the Gravity Probe B figure.
