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 using p5.js with thousands of particles, Perlin noise advection, fading trails, and shifting colors. Let me build this as a self-contained index.html file.

I've created a full-screen flow-field particle animation with the following features: 1. Thousands of particles (2000) moving according to Perlin noise flow field 2. Particles leave fading trails through a semi-transparent overlay technique 3. Color palette shifts gradually over time using HSB color mode 4. Responsive design that adapts to window resizing 5. Efficient grid-based flow field for performance The animation works by: - Creating a grid-based flow field using Perlin noise - Generating particles with random properties - Updating particle positions based on the flow field vectors - Drawing particles with fading trails using a semi-transparent background - Gradually shifting the color palette over time The visualization creates an organic, fluid motion as particles follow the noise-generated flow field, with colors cycling through the spectrum. Particles wrap around screen edges for a continuous effect. To run this, simply open the index.html file in a browser. The animation will automatically adapt to your screen size.

RUN
EVALUATION
Flow-field particle trails with colorful, evolving noise-driven streams; continuous animation, no visible interactivity beyond time evolution.
Vision grade · anthropic/claude-sonnet-5
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.
