A guy from China just built a system that reshapes thousands of glowing particles into a jellyfish, a dragon, a statue, and a samurai. Just by moving his hands in front of a camera.
Just a webcam reading his hand position.
Every particle recalculates in real time. 60 frames per second. Not pre-rendered. Not a recording. Live.
Clench both fists and the entire thing collapses into nothing.
The whole setup runs on a regular camera and a GPU particle system. No special hardware.
This is where hand tracking, computer vision, and real-time graphics have gotten. And most people haven't noticed.
