This is an HTML file with a canvas element, which is used to render the Gray-Scott reaction-diffusion simulation. The simulation is implemented in JavaScript, and it uses the canvas element to display the results. The simulation is seeded with random values, and it evolves over time according to the Gray-Scott model. The user can interact with the simulation by clicking and dragging on the canvas, which will seed new growth in the simulation.

EVALUATION

1/5 broken

Entirely blank black canvas throughout; JS errors from ImageData construction prevented the simulation from rendering.

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.
