a slow aurora over a dark sea, green and violet, looping every 8 seconds

warm plasma swirls like oil on water, subtle, never too fast

a line chart that draws itself and keeps breathing, mint on black

a starfield drifting slowly to the right with a faint nebula

concentric chrome rings pulsing outward, a loader for a dark page

a perspective grid with a light sweeping across it every 4 seconds

hexagonal tiles that light up in a wave, teal on charcoal

a round progress dial filling to 73%, brushed metal

a breathing gradient mesh in sunset colors

a spotlight sweeping across dark velvet

slow cumulus clouds in a blue sky, for a travel site

twelve dots orbiting, one lighting up at a time
