I've created a full-screen flow-field particle animation using p5.js. The animation features: 1. Thousands of particles that move according to Perlin noise vectors 2. Fading trails as particles move across the screen 3. Color shifting over time with a smooth gradient effect 4. Particles wrap around the edges of the screen 5. Responsive design that adjusts to window size The key components include: - A flow field generated using Perlin noise - Particle class with position, velocity, and lifespan attributes - Noise-based vector fields that guide particle movement - Color cycling through the hue spectrum - Fading trails created by reducing opacity over time The animation runs at full screen with no external dependencies, using only the provided p5.min.js file.
