A loudspeaker maker's hero beside the ferrofluid component: a glossy black pool of magnetic fluid in a shallow dish, seen from a low studio camera, always holds a crown of sharp needle spikes that grows and leans toward the cursor (or an invisible magnet hovering over the pool when idle) and settles back into a smooth dome, lit by key, strip and rim lights. An eyebrow, a heavy headline, an intro and two Arrow Pill buttons sit on the left. Every fluid setting passes through the fluid prop; the surface follows the theme.
