Playful Geometric Notation

Twittering Contraption

Four Bauhaus-style wire birds bob on a horizontal wire and chirp musical notes while a hand-crank below spins. Inspired by Bauhaus's 1922 painting.

When to use it

Art/creative portfolio backgrounds, generative-art showcases, ambient decorative tiles with a whimsical mechanical theme.

When not to

Light-theme UIs — background is hardcoded dark #23201b and won't adapt. Contexts needing interactivity.

Working with an AI agent

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

Increase bird count to 6 by changing N=4 to N=6, and slow the crank rotation from 4s to 8s in the kle06-spin animation. 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

  • bird count (N=4)
  • color palette (HUES array)
  • bob speed per bird (1.6+i*0.4 seconds)
  • crank spin duration (4s in kle06-spin)
  • wire vertical position (top:30%)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • IIFE wrapper
  • prefers-reduced-motion guard (REDUCED check)
  • aria-label on scene div for accessibility
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

  • Background color hardcoded to dark #23201b — must edit CSS to change
  • Bird positions are evenly spaced by formula; uneven layouts require manual overrides

  • Magic Square7x5 grid of color blocks in terracotta, teal, mustard, slate, and plum that slowly breathe — scaling and shifting saturation — evoking a Bauhaus…
  • A Line Goes WalkingA single ink line wanders the warm paper canvas step by step, tracing a random path from a teal start-dot to a terracotta head; fades and resets on a loop.
  • Arrow FieldA grid of colored arrows rotates and pulses in a slow flow-field current, each pointing direction driven by sine waves and radial angle from center.
  • Glyph GardenChildlike pictographs — fish, moon, arrow, face, tree, star, boat — drawn stroke-by-stroke on warm paper, held, then erased and reseeded in a cycling grid.
  • Polyphony GridA 16x6 color grid swept by a column playhead; active cells flash with scale and glow on each pass, voices re-seeded each lap for evolving compositions.
  • Colour Staircase9 color-graduated bars ascend like a staircase, each breathing in height and marching hue in staggered CSS keyframe loops. Warm parchment background.
