Animate this original artwork as a refined five-second website hero media asset. The exact transparent learning sphere rotates slightly while the small books, telescope, gears and scientific objects inside drift subtly in place. Preserve all objects and glass sphere silhouette; no merging or new objects. Preserve original identities, proportions, palette and materials. Locked camera unless explicitly specified. No zoom, cuts, text, UI, new objects or distorted anatomy. Continuous restrained motion; begin and end near the same composition where physically plausible.
