Cosmic & Space
Constellation Connect
46 drifting star nodes auto-connect with faint magenta lines when close; cursor draws lines to nearby stars and brightens them on hover.

When to use it
Dark-mode hero backgrounds, space/night themes, data-network metaphors, ambient looping screensavers.
When not to
Light backgrounds (hardcoded dark navy). Contexts needing legible text overlays — lines and motion compete with reading.
Working with an AI agent
Every component ships agent-ready metadata. An example instruction for this one:
Change node count from N=46 to 80, widen the connection threshold from LINK=0.2 to 0.28, and shift line color from rgb(218,62,140) to rgb(192,180,89) for a warmer gold palette.
Safe to edit
- node count (N=46)
- connection distance threshold (LINK=0.2)
- node drift speed (vx/vy *= 0.0006)
- line color (rgb(218,62,140))
- cursor influence radius (factor *4)
- twinkle speed (t += 0.02)
Keep intact
- DPR-aware canvas sizing
- visibilitychange pause/resume
- prefers-reduced-motion guard (freeze position, single frame)
- IIFE wrapper
Known limitations
- O(N²) proximity check — node counts above ~120 will strain low-end CPUs
- Background color hardcoded in CSS — must edit to change from dark navy
- Cursor lines disappear on touch devices (no persistent pointer position)
More Cosmic & Space components
- Orbiting Planet SystemFour glowing planets orbit a radiant sun on tilted elliptical rings with depth-sorted rendering; the system drifts subtly toward the pointer.
- Black-hole Accretion Swirl110 heat-colored particles spiral inward across a tilted accretion disk toward a glowing event horizon; pointer movement boosts swirl speed.
- Twinkling Starfield115 multicolor stars twinkle via sine waves; sparkle crosses appear on larger stars; stars brighten near cursor. Static fallback for reduced-motion.
- Spiral Galaxy Rotate115 stars form a two-armed spiral galaxy rotating around a violet radial-gradient core; pointer move briefly doubles spin speed.
- Comet Streak LoopCyan and violet comets with glowing heads and gradient tails streak diagonally across a twinkling dark starfield; click spawns an extra comet (up to 5).
- Ringed Planet RotateAmber gas giant with tilted Saturn-like rings slowly rotates over a twinkling starfield; pointermove adjusts ring tilt and light angle dynamically.
