The visualization animates a full-screen canvas of green noise that shifts between blurry and sharp textures over time. It initializes random green pixel values, then continuously reads and rewrites the image data using Canvas `getImageData` and `putImageData`. Each frame applies a simple convolution blur from neighboring pixels, then blends between that blurred result and a sharpened version based on the current pixel’s horizontal position and an incrementing time variable, creating a wave-like patterning effect across the screen.
