It needs thousands of particles advected by Perlin-noise vectors, leaving fading trails, with colors shifting over time. All in one self-contained index.html file with CSS in <style>, JS in <script>, and include <script src="p5.min.js"></script>.
I need to write the complete index.html file.
First, sketch the code.
Use global mode since p5.min.js global.

let cols, rows;
let res = 20;

createCanvas(windowWidth, windowHeight);
colorMode(HSB, 360, 100, 100);
cols = floor(width / res);
rows = floor(height / res);
flowField = new Array(cols * rows);

The file **index.html** has been created. Open it in a browser to view the full-screen flow-field particle animation (thousands of particles following evolving 3D Perlin noise vectors, with smooth fading trails and time-shifting HSB colors). Press **R** to reset or drag/touch to perturb the flow.
TAKE IT TO CODE
A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.
RUN
EVALUATION
Colorful flow-field particle trails animate continuously and respond visibly to click/drag/wheel/keys with perturbations.

MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
