Rubik's Cube Auto-Scramble and Solve 15-Second Animation

A roughly 15-second 3D animation of a Rubik's cube solving itself. It opens on the solved state, scrambles with 20 seeded random turns, then solves step by step with each turn animated, and ends with a small celebration. Built as a single-file Three.js r160 project, with a dark studio look and slow cinematic camera moves. The prompt spells out the timeline second by second. Suits explainer shorts about puzzles or as a code-animation example.
