From the README

"From blank canvas to a physics-based, hand-tracking engine in exactly 59.3 seconds."

This project is a real-time, interactive 3D particle system controlled entirely by hand gestures. It was architected and coded using Google's Gemini 3.0 inside AI Studio via advanced prompt engineering.

The application utilizes MediaPipe for skeletal hand tracking and Three.js for high-performance WebGL rendering, mapping 2D hand coordinates to a 3D volumetric space.

Ensure your webcam is enabled. The system detects your hand landmarks to drive the physics engine.
