🎡 Ferris Wheel at Night (2D)

This 2D companion strips the Ferris wheel down to a flat side view so the rotational kinematics are the whole point instead of a side effect of orbiting a 3D scene: the wheel's rotation speed, its 64 rim bulbs' colour, and how many of its 16 cabins glow are all live controls, and a readout panel tracks the wheel's angle θ, angular velocity ω, revolutions per minute, rotation period T = 2π / |ω|, and the cabins' tangential rim speed v = ω·r in real time. The cabins themselves stay axis-aligned as the wheel turns beneath them — the same rigid-body counter-rotation the 3D scene renders as a gimbal, here just a box that never rotates while its pivot orbits the hub.
