A grid of 10,000 circles animates in SVG, with each circle's radius pulsing between 0 and 20 pixels over a 20-second cycle while strokes display random RGB colors. The vanilla JavaScript creates circles dynamically using `document.createElementNS` and applies CSS keyframe animations to alter the `r` attribute. The piece references Sol LeWitt's generative grid aesthetics, using randomized stroke colors against unfilled shapes to produce a shifting, cellular pattern across the full browser viewport.
