Create a full-screen flocking simulation of boids using separation, alignment, and cohesion, drawn as oriented triangles that steer smoothly and flee from the mouse cursor.

The user wants a flocking simulation (boids algorithm) in a single HTML file. This should include: 1. Full-screen canvas 2. Boids drawn as oriented triangles 3. Three main behaviors: separation, alignment, and cohesion 4. Smooth steering 5. Boids should flee from the mouse cursor Let me create a comprehensive single-file solution with: - Canvas setup - Boid class with position, velocity, acceleration - Separation, alignment, cohesion behaviors - Mouse avoidance behavior - Smooth steering using velocity and acceleration limits - Triangle rendering oriented in the direction of velocity I'll write this all in one index.html file.

I've created a complete flocking simulation in a single HTML file. Let me verify it works by checking the file exists and maybe running a quick test to see if it renders properly.

The file is created successfully. It's 15KB and contains: 1. Full-screen canvas setup 2. Boid class with position, velocity, acceleration 3. Three flocking behaviors: separation, alignment, cohesion 4. Mouse avoidance behavior 5. Oriented triangle rendering 6. Controls for adjusting parameters 7. Visual effects like gradients and glow The simulation should work right away when opened in a browser. Let me verify it works by checking if we can open it.
I've created a complete flocking simulation in `index.html`. The application features: **Core Features:** - **200 boids** rendered as oriented triangles that point in their direction of movement - **Three flocking behaviors:** - **Separation** - Boids avoid crowding neighbors - **Alignment** - Boids steer toward the average heading of nearby flock members - **Cohesion** - Boids move toward the center of mass of nearby flock members - **Mouse avoidance** - Boids flee from your cursor (with adjustable fear distance) - **Smooth steering** - Uses velocity and acceleration with proper limits **Visual Effects:** - Colorful gradients (cyan to blue) that shift based on velocity direction - Glowing triangle shapes - Motion blur trail effect - Pulsing mouse cursor indicator **Interactive Controls:** - Separation strength - Alignment strength - Cohesion strength - Mouse fear/flee distance - Maximum speed Just open `index.html` in any modern browser to see the simulation running. Move your mouse around the screen and watch the flock scatter and regroup!
