Paint dancing on a speaker: a black rubber speaker cone lying flat, covered with blobs of thick saturated paint in electric blue, hot pink, yellow and orange, against a pitch black background. First 2 seconds: a deep bass pulse makes the paint jump up into trembling columns and crown splashes. Next 2 seconds: the columns branch into fingers and droplets that leap higher and fall back, the colours folding into each other. Final second: one big pulse throws a fountain of droplets up, then the paint settles into a quivering marbled puddle. Macro, slow motion, hard top light, static locked-off camera. No text, no logos
