# Ferrofluid

> Interactive magnetic ferrofluid: a glossy blob that grows sharp spikes toward your cursor and bursts outward on click, tap, Enter or Space. Themed from your shadcn tokens (chart colors for the oil-slick sheen, background/foreground for the fluid), works in light and dark, respects reduced motion, and has zero dependencies.
