Prompt for this run

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.

The user wants me to create a single-page web app with a flow-field particle animation using p5.js. The requirements are:
1. Single self-contained index.html file
2. CSS in <style> tag, JS in <script> tag - inline
3. No external resources/CDNs/network requests
4. Use the pre-provided p5.min.js library
5. Full-screen flow-field particle animation with:
   - Thousands of particles
   - Perlin noise vectors for advection
   - Fading trails
   - Colors shifting over time

Let me create this file with all the necessary code.

→ write index.html (3732 bytes)

The file has been created. Let me verify it exists and is correct.

→ bash {"command":"ls -la index.html && head -20 index.html"}

toolResult

-rw-r--r--. 1 node node 3732 Aug 1 20:24 index.html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Flow Field Particles</title> <style> * { margin: 0; padding: 0; box-sizing: border-box; } body { overflow: hidden; background: #000; } canvas { display: block; } </style>

The file has been created successfully. Let me verify that p5.min.js is also present in the directory as expected.

→ bash {"command":"ls -la p5.min.js"}

toolResult

-rw-r--r--. 1 node node 1034532 Aug 1 20:24 p5.min.js

Both files are present. The index.html is ready and will use the local p5.min.js file. Let me summarize what I've created.

Created `index.html` with a full-screen flow-field particle animation featuring: - **3000 particles** advected by Perlin noise vectors - **Flow field grid** (20px scale) generating smooth directional forces using 3D Perlin noise (x, y, z-time) - **Fading trails** via semi-transparent black overlay (`alpha=2`) creating motion blur effect - **Color shifting** over time using HSB color mode with global hue offset + individual particle hue variation - **Particle wrapping** at canvas edges for continuous flow - **Responsive** - handles window resize events To view: Open `index.html` in a browser. The particles will dance across the screen following organic flow patterns that evolve over time.
