Murmur Particle Field Hero

Murmur is a hero section whose backdrop is alive. Tens of thousands of tiny points drift as one body, curling through a flow field computed entirely on the graphics card, and every twenty-odd seconds the whole cloud breathes from a wide undulating ribbon into a loose sphere and back, each particle leaving at its own moment so the change rolls through the crowd like a wave. Move the pointer and the field leans toward you and parts around the cursor with a soft ripple that glints in one accent colour. The look is cinematic: a depth-of-field pass swells and softens distant points, a few become lens-style bokeh discs, soft halos add glow, and a hot thread runs down the middle of the ribbon, all graded over a dark olive backdrop with film grain and a faint lens reticle. The palette stays narrow, warm off-white points with chartreuse and a rare apricot core, and a light theme turns the same scene into ink dust and green bokeh on paper. It suits studios, launches and product pages that want a first screen people remember, and it is built to be responsible: one draw call, pixel ratio capped, rendering paused when offscreen, a still frame for reduced motion and a designed poster when WebGL is missing.
