The user wants me to create a full-screen flow-field particle animation using p5.js. The requirements are: 1. Thousands of particles 2. Advected by Perlin-noise vectors (flow field) 3. Fading trails 4. Colors shifting over time 5. Must be self-contained in index.html 6. Use the pre-provided p5.min.js Let me create a beautiful flow field visualization with these features.

I've created the flow field particle animation. Let me verify the file was written correctly.
Created `/workspace/index.html` with a full-screen flow-field particle animation featuring: **Key Features:** - **3000 particles** advected through a Perlin noise-based vector field - **Fading trails** via semi-transparent black overlay each frame - **Dynamic colors** shifting over time using HSB color mode with hue mapped to flow angle + global offset - **3D Perlin noise** (x, y, z) for smooth temporal evolution of the flow field - **Particle wrapping** at edges for seamless infinite canvas effect **Interactions:** - **Click** - burst of particles spawns at cursor position - **Press 'R'** - reset all particles - **Window resize** - automatically adapts to new dimensions The flow field is computed on a grid using Perlin noise, creating organic swirling patterns. Particles follow the field vectors while leaving luminous fading trails, with colors smoothly cycling through the spectrum as the noise evolves.

EVALUATION
Flow-field particles create colorful trails, but far too few particles—not the dense thousands requested—leaving mostly black screen.
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.
