**Developing Boids Simulation** I'm currently focused on the core boids behavior, specifically implementing separation, alignment, and cohesion following Reynolds' rules. I'm representing each boid as an oriented triangle to give them a clear direction. Next, I plan to work on smooth steering and mouse-cursor interaction, for fleeing behavior. **Refining Boid Implementation** I've been working on creating a single, self-contained HTML file. This involves using canvas for animation, and building a `Boid` class to store all the properties. The main loop is set up to update and draw the boids. I am currently fleshing out the math for separation, alignment, and cohesion behaviors, along with mouse avoidance. I'm also styling the visuals for a fullscreen black background and white boids, all within the constraints of the single file.

The flocking simulation is complete and contained in `index.html`. It uses a canvas element to render approximately 100 boids that follow Reynolds' rules (Separation, Alignment, Cohesion) and react to mouse movement by fleeing. You can open `index.html` in any modern web browser to view the simulation.

EVALUATION
Boids animate as tiny triangles moving on a black screen; flocking behavior is barely visible and inputs show no clear reaction.

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.
