Background
Particle Flow
A live particle flow: smoky trails of thousands of particles run along a direction field, gathering into clouds and dispersing. GPU-rendered, zero dependencies. For AI products, data, science and anything that needs motion without noise.
What you can change
- speed — still, calm or lively; still draws a single frame with no loop
- intensity — faint, soft or bright: the accent strength; soft by default so the background does not fight the content
- density — sparse (700) or dense (1600): the particle count and frame cost
A link for your AI agent: preview, code and instructions.

- 1. Copy the link.
- 2. Write to your agent in your own words and drop the link into the sentence.
- 3. The agent opens the link and installs the component from the registry.

Technical notes
One file, zero dependencies, "use client", canvas2D without WebGL. Up to 1600 particles in flat Float32Arrays follow a direction field from simplex noise (a table-free JS implementation); the frame is not cleared but dimmed with a translucent fill of the base color — trails fade on their own. The palette is CSS variables with light-dark read through the canvas computed border-color. DPR ≤ 1.5 for thin lines. Paused outside the viewport and in a hidden tab, prefers-reduced-motion and speed=still draw a single pre-warmed frame (40 steps), a radial-gradient fallback until the first frame. Palette --vibeui-surface-013-*.
