A 3D starfield animation displays 800 colorful stars wiggling through dark space with a rotating perspective and a continuous hue shift across the color spectrum. Each star, generated with random positions, sizes, and speeds, undulates via sinusoidal wave functions and recycles when moving off-screen. The animation uses vanilla JavaScript with Canvas API for rendering, `requestAnimationFrame` for smooth looping, and a CSS `hue-rotate` filter applied to the canvas each frame to create the dynamic color shifting effect.
