I've successfully created a full-screen flocking simulation with boids that exhibit separation, alignment, and cohesion behaviors. The simulation features: 1. **Smooth Steering**: Boids move with velocity-based physics and smooth orientation changes 2. **Flocking Behaviors**: - Separation: Avoid crowding neighbors - Alignment: Steer towards average heading of neighbors - Cohesion: Move towards average position of neighbors 3. **Mouse Interaction**: Boids flee from the mouse cursor 4. **Visual Design**: - Attractive gradient background - Colorful triangular boids that orient based on their velocity - Semi-transparent trails for a smooth visual effect - Control panel with statistics and buttons 5. **Interactive Controls**: - "Add Boids" button to increase the flock size - "Reset" button to restart the simulation 6. **Responsive Design**: Adjusts to any screen size 7. **Performance Optimized**: Efficient algorithm with proper force limiting The boids are drawn as oriented triangles that smoothly transition their orientation based on velocity, creating a visually appealing flocking effect. They maintain separation, align with neighbors, and cohere towards group centers while avoiding the mouse cursor. All code is contained in a single HTML file with no external dependencies.

RUN
EVALUATION
Boids flock with trailing motion but appear as smeared blobs rather than clear oriented triangles; animates continuously, mouse cursor circle visible but flocking clusters look messy.

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.
