A 3D grid of 64 color-shaded spheres arranged in a cube rotates slowly under directional and ambient lighting. The spheres use HSL coloring based on their grid coordinates, creating a gradient across the form. Rendered with Three.js WebGL, the scene uses `OrbitControls` for interactive camera movement, allowing viewers to orbit, pan, and zoom. The animation loop incrementally rotates the sphere group on both the X and Y axes.
