20 Subjective Realities - Standalone 3D Visualization

Prompt

Create an interactive 3D visualization showing 20 people at a specific event, where each person perceives the room completely differently (e.g., one is convinced everyone is secretly sad, another is sure everyone is euphoric/high, etc.). Only two technical constraints: 1. Since you cannot generate a binary 3D asset file, implement this as a complete, runnable, single-file interactive HTML page that renders directly in the browser. 2. Zero external dependencies: The code must run 100% locally and offline without loading any external libraries, CDNs, or web fonts (fully self-contained and network-independent). Beyond that, take full creative freedom with the character design, setting, mood shifts, and how these subjective realities are expressed visually and interactively.
