Cosmic & Space
Logarithmic Zoom Journey
Nested labeled rings dilate outward from a glowing core through 10 cosmic scales (atom to cosmic web); pointer and click accelerate the zoom drift.

When to use it
Space-themed hero backgrounds, science/data viz intros, ambient screensaver-style displays needing infinite-zoom metaphor.
When not to
Light-background layouts (background hardcoded dark navy). Contexts where label text competes with page content.
Working with an AI agent
Every component ships agent-ready metadata. An example instruction for this one:
Change RUNGS labels and colors to geological timescales, set GAP to 2.0 to widen ring spacing, and increase baseR from U*0.052 to U*0.065.
Safe to edit
- zoom speed (t increment divisor 520)
- ring gap (GAP=1.7)
- base ring size (baseR=U*0.052)
- rung labels and colors (RUNGS array)
- pointer boost strength (0.25 / cap 2.2)
- dot count per rung (dots property)
Keep intact
- DPR-aware canvas sizing
- visibilitychange pause/resume
- reduced-motion static-frame fallback
- IIFE wrapper
Known limitations
- Background color hardcoded in CSS and canvas fillRect — must change both to alter background
- Reduced-motion fallback is a single static frame, not a fully static layout
- ringAt() helper function is defined but unused — actual radius computed inline
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.
