Ferrofluid
About
Ferrofluid by Robert Leitl is a sound-reactive study of black magnetic liquid. A glossy puddle sits on a dark surface, raised into dozens of sharp spikes that catch thin highlights along their edges. A small microphone icon at the bottom asks for access, and when you whistle or speak into it, the liquid shivers, spikes higher and then collapses back into rounded bumps. The screen is almost bare, so the shape of the fluid takes all the attention. It runs in WebGL2 with custom shaders, noise and particles, and the page is under a megabyte.
