UI Micro-interactions

Inverted Reading Glass

A white circular lens tracks the cursor using mix-blend-mode:difference, inverting text colors beneath it to reveal near-invisible dark text on black.

When to use it

Hero sections with hidden or low-contrast text that rewards exploration. Interactive art installations or editorial reveals.

When not to

Contexts requiring legible text without interaction. Touch drag explores the lens; reduced motion reveals all text and moves the lens without easing.

Working with an AI agent

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

Change the lens size from clamp(150px, 20vw, 250px) to clamp(80px, 12vw, 140px) and set the lerp factor from 0.15 to 0.08 for a heavier lag effect.

Safe to edit

  • lens diameter (clamp(150px, 20vw, 250px))
  • lerp smoothing factor (0.15)
  • text content (.text-content span)
  • text base color (#333333)
  • auto-orbit radius multiplier (0.1)

Keep intact

  • mix-blend-mode: difference on .lens
  • IIFE wrapper
  • visibilitychange stop/start
  • prefersReducedMotion guard
  • demo-v1 preview lifecycle: initialize demoEnabled from window.__foreverPreview and stop attract work on the window forever:interactive event; retain manual feedback, settling, cleanup and explicit sessions

Known limitations

  • Text is nearly invisible without interaction — not accessible as standalone content
  • Reduced motion reveals all text; deliberate input moves the lens immediately without ambient motion.
  • Auto-orbit loop runs a second rAF loop alongside animate() — two concurrent rAF chains
  • State remains local to each mounted instance; format/theme remount preserves takeover, not component values.
