Playful Geometric Notation

Colour Staircase

9 color-graduated bars ascend like a staircase, each breathing in height and marching hue in staggered CSS keyframe loops. Warm parchment background.

When to use it

Art-themed dashboards, Bauhaus or Bauhaus visual contexts, ambient looping backgrounds with a structured color palette feel.

When not to

Contexts requiring legible text overlays — the rising bars occupy full height. Avoid when a static, non-animated background is needed.

Working with an AI agent

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

Change the ribbon palette to cool blues by replacing ribbon with ['#1a3a5c','#2a5f8f','#3a8fc4','#6ab8d4','#a0d8ef'], and increase step count N from 9 to 12. 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

  • color ribbon array (ribbon)
  • step count (N=9)
  • height range (base=24+t*52, ±4/+16)
  • breathe/march timing (--bd/--bdel/--md/--mdel per block, 3.2–4.8 s / 4–7 s)
  • hue-rotate amount (20deg) in kle07-march
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • IIFE wrapper
  • .kle07-step height:100% (the blocks' % heights resolve against it; without it the tile paints blank)
  • visibilitychange pause (kle07-paused class)
  • prefers-reduced-motion guard (kle07-still class + @media animation:none)
  • role=img + aria-label on stage div
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

  • Staggered negative animation-delay means first few bars start mid-cycle on load

  • 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.
  • Twittering ContraptionFour 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.
