Vortex Background Component is a single JavaScript file, vortex.js, that adds a swirling ring of up to 160,000 GPU particles behind any section of your site. Call Vortex.create() or add a data-vortex attribute and it appends a click-through canvas, handles sizing, pointer interaction, pausing and cleanup for you.

The download also includes a complete landing page that doubles as documentation: a hero using the component, a feature overview, a playground with sliders for particle count, speed, radius, thickness, size, brightness, interaction and colours that generates your configuration snippet live, an options reference table, install steps and an FAQ.

The component is written in raw WebGL with its own tiny matrix maths, so there are no libraries, no CDN calls and no build step. It is honest about being a lightweight effect, not a general 3D engine: one scene, one ring, tuned well. If WebGL is unavailable a Canvas2D renderer takes over with a capped particle count.
