Using the pre-provided p5.min.js (global p5, instance or global mode), create a full-screen flow-field particle animation: thousands of particles advected by Perlin-noise vectors, leaving fading trails, with colors shifting over time.

I'll create a full-screen flow field particle animation with thousands of particles advected by Perlin noise, leaving trails that fade over time and have colors shifting over time. This will be a self-contained index.html file, loading p5.min.js and including the complete script. I'll proceed to generate this code now.

I have created a complete self-contained `index.html` file with the flow field particle animation. You can open this file in a browser to see thousands of particles advected by Perlin noise, leaving fading trails with shifting colors. Would you like me to assist with anything else?

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.

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.
