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.
thinking
The user wants a boids flocking simulation with: 1. Separation, alignment, and cohesion behaviors 2. Drawn as oriented triangles 3. Smooth steering 4. Flee from mouse cursor 5. Full-screen I'll create a single HTML file with embedded CSS and JS. The simulation will use the classic Reynolds boids algorithm with: - Separation: steer to avoid crowding local flockmates - Alignment: steer towards the average heading of local flockmates - Cohesion: steer to move toward the average position of local flockmates - Plus mouse avoidance (flee behavior) Let me write this as a complete, self-contained file.

I've created a complete boids flocking simulation. Let me verify the file was created correctly.

The file has been created successfully. Let me verify it's valid HTML by checking for basic structure.

The file is complete and valid. Let me provide a summary to the user.
Done! I've created a full-screen boids flocking simulation in `/tmp/ws/index.html`. **Features implemented:** - **150 boids** rendered as oriented triangles with gradient fills and subtle glow - **Three flocking behaviors:** - **Separation** - avoid crowding neighbors - **Alignment** - steer toward average heading of neighbors - **Cohesion** - steer toward average position of neighbors - **Mouse flee behavior** - boids scatter when the cursor approaches (shown with a red circle indicator) - **Smooth steering** with max force limits - **Trail effect** for visual appeal - **Touch support** for mobile devices - **FPS counter** in the bottom-left corner The boids have varied colors from a vibrant palette and wrap around screen edges. Open `index.html` in a browser to see the simulation in action!
TAKE IT TO CODE
A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.
RUN
EVALUATION
Colorful flocking boids animate continuously with fleeing behavior visible around the mouse cursor circle (visible pointer indicator).

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.
