An LED-wall background for React: a pinwheel of silver-white light sprays outward from its center like vapor, seen through soft square LED cells, in WebGPU.

THE SYSTEM BEHIND THE SURFACE
Inside LED Bloom.
LED Bloom paints a pinwheel of overlapping petals of silver-white light that meet in thin seams at its center, measured from a reference still, and shows it on an LED wall: soft square cells, a little uneven, whose gaps the brightest light floods. Its paint sprays outward from the center like vapor: the petals curl and drift as they travel, come out in puffs that spiral away and thin before they spread far, while new paint keeps coming from the middle. The pointer scatters the LEDs: the cells round it are tossed outward, each a little its own way and a little smaller, leaving a dark clearing with the wall's light thrown to its edge, and they fall back into place when it moves on. Hover set to Glow lights the cells under the pointer instead.
LED Bloom shows its own bloom of light; it does not put your images or video on the LED wall, and it is not a physical fluid simulation.
