Particle Hands
We made fifteen thousand particles chase your hands in real time.
A gesture-driven particle instrument that runs in a browser tab. Up to fifteen thousand GPU-rendered particles swarm to the joints of your hands through a webcam, sculpting a glowing, two-toned silhouette that reacts to every move.
Most webcam AI demos look like tech demos: debug overlays, default fonts, neon grids. The aim here was something between an art piece and an instrument. Confident enough to screenshot, tactile enough to still be playing with three minutes in.
Hands behave like gravitational bodies. Particles are recruited to twenty-one tracked landmarks and the bones between them, then dissolve back into ambient drift when the hand leaves the frame.
The whole thing holds sixty frames a second on top of a live hand-tracking layer, on ordinary hardware, with no native code. All processing stays on the device. The webcam feed never leaves the browser.
