The flocking boids simulation has been successfully created in `index.html`. The simulation features: - 150 boids that exhibit the three classic flocking behaviors: - **Separation**: boids steer to avoid crowding neighbors - **Alignment**: boids steer toward the average heading of local flockmates - **Cohesion**: boids steer toward the average position of local flockmates - Boids are drawn as oriented triangles that point in their direction of motion - Boids smoothly flee from the mouse cursor within a 150px radius - Full-screen canvas with edge wrapping - Real-time mouse tracking that influences boid behavior The implementation is entirely self-contained in a single HTML file with no external dependencies. You can open `index.html` in any modern browser to see the simulation in action. The boids will form cohesive flocks that move together while maintaining personal space, aligning their direction, and fluidly avoiding the mouse cursor when it approaches.

EVALUATION

3/5 working

Boids flock and swirl as small oriented particles on black; animates continuously but inputs show no distinct fleeing behavior.

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.
