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 a full-screen flow-field particle animation using p5.js. Let me create a single HTML file with inline CSS and JavaScript that:
1. Uses the pre-provided p5.min.js
2. Creates thousands of particles advected by Perlin noise vectors
3. Has fading trails
4. Colors shift over time
5. Full-screen

I'll write this as a single index.html file.

→ write /workspace/index.html (4761 bytes)

toolResult

Successfully wrote 4761 bytes to /workspace/index.html

I've created the index.html file with a full-screen flow-field particle animation using p5.js. Let me verify it exists and check if p5.min.js is present in the workspace.

→ bash {"command":"ls -la /workspace/"}

Both files are present. The index.html is created and p5.min.js is already in the workspace. The task is complete.

Done. Created `/workspace/index.html` with a full-screen flow-field particle animation featuring: - **6000 particles** advected by a Perlin-noise vector field (3D noise with animated z-offset) - **Fading trails** via semi-transparent background (`background(0, 0, 0, 0.08)`) - **Color shifting** over time using HSB mode with global `hueOffset` + position-based variation - **Dynamic line weights** based on particle velocity - **Particle lifecycle** — particles reset after random lifetime for continuous renewal - **Wrap-around edges** for seamless flow - **Responsive** — handles window resize Open `index.html` in a browser to view.
