Abstract Geometric Improvisations
Several Circles
13 coloured discs drift and pulse on a charcoal ground with blend-mode overlaps and halos; a pale diagonal line sways below. An abstract composition.

When to use it
Art-inspired hero backgrounds, ambient gallery displays, or contexts wanting painterly generative motion with a fine-art reference.
When not to
Layouts needing legible content overlaid or a light background — the dark ground and blended circles compete with text.
Working with an AI agent
Every component ships agent-ready metadata. An example instruction for this one:
Change the circle count from N=13 to N=20, add '#ff6b00' to the cols array, and slow drift by changing the max duration from 18 to 28 seconds. 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
- circle count (N=13)
- color palette (cols array)
- drift distance (--dx/--dy range +/-30px)
- drift duration (9-18s range)
- halo probability (Math.random()<0.5)
- theme tokens (:root dark defaults + [data-theme=light] overrides)
Keep intact
- IIFE wrapper
- prefers-reduced-motion guard (REDUCED check on all animations)
- role=img + aria-label on stage div
- theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)
Known limitations
- Circle positions randomised each load — layout not deterministic
- Background color hardcoded (#17151a) — edit CSS to change dark ground
More Abstract Geometric Improvisations components
- 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.
- Yellow-Red-Blue Counterpoint24 bars in yellow, red, and cobalt rise and fall in sine-wave counterpoint on warm paper, echoing abstract's three-voice color theory.
- 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.
