30Displacement — the surface ripples where you touch it
Liquid on hover
Turbulence drives a displacement map over the plate, and the channels separate a little at the edges. The whole thing is one SVG filter — no WebGL, no library.
Hover the plate. The noise frequency and the displacement scale both ride your distance from the centre.
