Pulse v6 — Sonar
Five bullseyes pinned around the centre — blue, green, violet, yellow, red — with rings of light rippling through each like pings from deep water.
Five ringed discs sit fixed in a ring, one per hue, and concentric bands of light ripple through each of them, expanding like a sonar ping through still water. Nothing else moves.
This is the version where geometry stops moving entirely: the five dots never change position or radius, and all animation lives in brightness. A sine wave travels along each fat-to-thin stroke stack, and wherever it crests the buried layers flash through, reading as rings sweeping across a solid disc.
