Ransom Assembly

Mixed-font letters on cut-paper swatches fly in from random edges and spring-tumble into RANSOM, then reassemble. Click to restart.

When to use it

Dark hero sections needing dramatic kinetic type. Title screens, creative portfolio intros, or thriller-themed UIs.

When not to

Contexts requiring readable static text at all times — letters are off-screen between cycles. Low-end mobile may stutter.

Working with an AI agent

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

Change WORD to 'HELLO', swap ACC to '#f4a261', and increase spring stiffness from 0.10 to 0.18 so letters snap into place faster. 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

  • target word (WORD constant)
  • accent color (ACC = #e63946)
  • spring stiffness range (0.10 + random*0.05)
  • damping range (0.78 + random*0.06)
  • font families array (fams)
  • settle hold duration (settleHold > 120 frames)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • DPR-aware canvas sizing and ctx.setTransform
  • visibilitychange stop/start guard
  • prefers-reduced-motion static fallback
  • glyphW cache (measureText called once in layout, not per frame)
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

  • WORD is hardcoded to 6 chars — fams/wts/caseFlip/wsc arrays must be extended to match if word length changes
  • Background color hardcoded in both BG constant and CSS — two places to update
  • Pointer nudge only works on unsettled glyphs

More Kinetic Typography components

  • Weight Morph WaveEach letter of a word pulses font-weight and vertical scale in a staggered sine wave, shifting hue from cyan to blue.
  • Scramble DecodeNeon-green monospace words scramble through random glyphs then lock left-to-right like a terminal decrypting. Auto-cycles; click skips to next word.
  • Split-Flap BoardSix amber tiles cycle through letters to spell airport-style words (DEPART, ARRIVE, ONTIME, BOARDS) on a dark charcoal background with a rotateX flip…
  • Gradient ShimmerBold "SHIMMER" text with a rainbow gradient clipped to the letterforms, continuously panning for a glossy iridescent sweep on deep umber.
  • Glitch RGB SplitRed and cyan pseudo-element copies of GLITCH drift and randomly snap with clipped displacement, simulating a CRT RGB-split glitch on near-black.
  • Marquee TickerTwo rows of bold words scroll in opposite directions — yellow left, teal right — with red bullet separators on a dark green background, news-ticker style.
