Cosmic & Space
Tidal Spaghettification
170 particles arc past a gravity well, stretching into a white-hot filament at perihelion. Pointer and click boost the tidal spread effect.

When to use it
Dark space or sci-fi hero backgrounds, physics visualizations, ambient loading screens with dramatic motion.
When not to
Light-background UIs (background hardcoded dark purple-black). Layouts where high-motion visuals compete with primary content.
Working with an AI agent
Every component ships agent-ready metadata. An example instruction for this one:
Change particle count N from 170 to 220, shift the color ramp to cyan/blue (replace #fff0e6, #ffb3a0, #ff6b6b, #8a3a6a with #e6f8ff, #a0d4ff, #6b9eff, #3a5a8a), and slow flow by reducing t+=0.0042 to t+=0.002.
Safe to edit
- particle count (N=170)
- flow speed (t += 0.0042)
- color ramp (4 heat-threshold hex values)
- perihelion radius (peri=42*S)
- tidal spread strength (0.4+boost multiplier)
Keep intact
- IIFE wrapper
- prefers-reduced-motion guard with static fallback frame
- visibilitychange stop/start pattern
- DPR-aware canvas sizing
Known limitations
- Background color hardcoded in CSS (#0a0510) — must change both CSS and canvas fillStyle to retheme
- Gravity well position fixed relative to center — may clip on very wide or narrow viewports
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.
