Abstract Geometric Improvisations

Yellow-Red-Blue Counterpoint

24 bars in yellow, red, and cobalt rise and fall in sine-wave counterpoint on warm paper, echoing abstract's three-voice color theory.

When to use it

Ambient backgrounds or art-themed hero sections where abstract or abstract expressionism is the visual language.

When not to

Contexts requiring text legibility over the animation, or layouts where full-viewport fixed positioning conflicts with page scroll.

Working with an AI agent

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

Change column count from N=24 to N=36, slow all voice frequencies by half (1.1→0.55, 1.7→0.85, 0.7→0.35), and set PAL.red to '#e8600f'. 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

  • column count (N=24)
  • palette colors (PAL.yellow/red/blue)
  • voice frequencies (1.1, 1.7, 0.7)
  • bar height range (12+v*84)
  • transition speed (.12s linear)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • IIFE wrapper
  • .kan05-col height:100% (the bars' % heights resolve against it; without it the tile paints blank)
  • prefers-reduced-motion guard with static fallback
  • visibilitychange pause/resume
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

  • Background color hardcoded in CSS (#f4efe2) — must edit to change from warm paper
  • No hover or click interaction — purely autonomous

  • Several Circles13 coloured discs drift and pulse on a charcoal ground with blend-mode overlaps and halos; a pale diagonal line sways below. An abstract composition.
  • Singing CompositionTriangles, arcs, circles and lines in Bauhaus primaries spawn, breathe and dissolve on warm paper in an endless generative composition inspired by abstract.
  • The Rhythm ScoreA red playhead sweeps 16-step staves of blue circles, yellow triangles, and red squares; each note flares in size and opacity as the head crosses it.
  • Concentric ResonanceColored rings burst outward from random points on a dark field, fading as they expand — abstract's concentric forms in perpetual motion.
  • The Orbiting TroikaThree colored spheres (blue, yellow, vermilion) orbit a black sun at harmonic speeds, leaving fading color trails that form a slowly turning rosette.
  • Checkerboard FugueA diagonal wave sweeps a 10x8 CSS grid, lighting each cell in Bauhaus green, yellow, red, and black before returning it to a warm paper tone.
