A contemporary art foundation hero over the ink-fluid background component: a real-time stable fluids simulation where indigo, vermilion and graphite pigments swirl through water on a ground taken from the foreground token, glowing like light on a dark ground and mixing like ink on a light one. The cursor drags ink, clicks switch pigment and drops land on their own on touch screens. A bold serif headline, a short description, an Arrow Pill and an underline link sit on top. Every simulation setting passes through the ink prop.
