Trip Tunnel

26 lobed concentric rings recede into a glowing magenta vanishing point, cycling a Fillmore-poster palette across a slow inward perspective tunnel.

When to use it

Dark-mode hero backgrounds, music/festival visuals, ambient screensavers, psychedelic or retro-poster themed sections.

When not to

Light backgrounds (dark navy hardcoded). Any context where constant motion competes with readable text overlays.

Working with an AI agent

Every component ships agent-ready metadata. An example instruction for this one:

Change LOBES from 7 to 5, swap PAL to a cool blue/green palette ([[40,180,255],[60,235,180],[120,255,80],[0,120,200],[80,220,255]]), and slow the tunnel cycle to 35 seconds by changing the /22 divisor. Theme: dark tokens live in :root, the light variant in :root[data-theme="light"]; ?theme=light or a {type:'forever:theme'} postMessage switches at runtime.

Safe to edit

  • ring count (RINGS=26)
  • lobe count (LOBES=7)
  • palette array (PAL)
  • tunnel cycle speed (/22 divisor)
  • lobe amplitude factor (0.16*z)
  • perspective compression (EXP=2.05)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • IIFE wrapper
  • prefers-reduced-motion guard (staticFrame fallback)
  • visibilitychange pause/resume
  • opaque wipe per frame (prevents trail accumulation)
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

  • Background color hardcoded in both CSS and canvas fillRect — must change both to retheme
  • No pointer interactivity — fully passive
  • 26 stroked paths per frame; may be slow on very low-end mobile at large viewport sizes
