How the movement works

Use it for music videos, live backdrops or dreamy scene changes, wherever a pattern has to hold up on repeat.

1. 01The area around the centre is split into eight 45° wedges; every other wedge is drawn mirrored, giving eight mirror-symmetric sections.
2. 02One wedge holds 13 shapes (circles, diamonds, triangles; four colours; fixed random seed). They travel outward from the centre to radius 300, one full radius per 4.7 s, wrapping back to the centre.
3. 03Shapes grow as they go out ((5 + 0.1r) × 0.7–1.4) and spin 0.02 rad per px. They fade in over the first 30 px and out over the last 70 px; each sways ±0.08 rad once per 4.7 s.
4. 04The whole pattern turns 90° per 4.7 s (two wedges, so the loop joins up).
5. 05A white eight-point star at the centre (radius 20 ± 4, pulsing twice per 4.7 s).
