Aurora Ribbons
Three glowing aurora bands in green and violet ripple and sway over a twinkling starfield; pointer steers the horizontal drift of all ribbons.

When to use it
Dark-mode hero backgrounds, nature/space themes, ambient screensaver-style loops, dashboard backgrounds.
When not to
Light backgrounds (sky hardcoded dark navy). Contexts with text overlaid directly on ribbons — the additive blend can obscure copy.
Working with an AI agent
Every component ships agent-ready metadata. An example instruction for this one:
Add a fourth band with hue [40,60] (gold/amber) at base 0.28 and amp 0.08 to simulate a lower atmospheric glow layer.
Safe to edit
- band hue ranges (b.hue arrays)
- band vertical base positions (base property)
- pointer sway strength (60 multiplier)
- star count (Math.min(70, ...))
- ribbon column count (cols=18)
Keep intact
- globalCompositeOperation='lighter' for additive glow blend
- DPR-aware canvas sizing
- visibilitychange pause guard
- reduced-motion t increment freeze
Known limitations
- Background color hardcoded in CSS (#040814) — must edit to change dark sky
- No reduced-motion static fallback — animation halts but canvas is blank when reduce=true and t never advances
- Per-column gradient creation (18x3 per frame) may be slow on very low-end devices
More Organic & Nature components
- Growing VineA sinuous green vine grows upward sprouting 14 alternating leaves and a pale bud tip, then retracts in a seamless loop on a dark forest background.
- Flickering FireAdditive-blended ember particles rise from a glowing orange base, flickering like a real flame; cursor pans left/right to fan the fire sideways.
- Water RippleConcentric ripple rings expand across a deep teal water surface with shimmering caustic bands; tap anywhere to drop a new ripple. Auto-drops periodically.
- Lightning BoltJagged lightning bolts with branching forks strike randomly down a dark storm-sky canvas; screen flashes rust-white on each strike. Tap to trigger instantly.
- Falling SnowUp to 110 depth-layered snowflakes drift and sway down a dark blue gradient; pointer movement shifts a wind force that nudges the entire flurry sideways.
- Drifting CloudsPuffy white clouds with radial-gradient puffs and soft blue undersides drift across a layered sky gradient; pointer nudges them forward.
