Abstract Geometric Improvisations
Concentric Resonance
Colored rings burst outward from random points on a dark field, fading as they expand — abstract's concentric forms in perpetual motion.

When to use it
Art-themed hero backgrounds, ambient displays, dark-mode canvases needing gentle generative motion.
When not to
Light backgrounds (hardcoded dark bg). Contexts requiring user interaction — it runs fully autonomously with no pointer response.
Working with an AI agent
Every component ships agent-ready metadata. An example instruction for this one:
Change the auto-strike interval from 1.4s to 0.8s, add PAL.green as a third ring color alternate, and increase ring count per strike from 4 to 6. 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
- auto-strike interval (autoT > 1.4)
- ring count per strike (i < 4)
- ring speed range (sp: 60 + i*22)
- color palette (cols array)
- fade duration (g.t/2.4)
- max rings cap (80)
- theme tokens (:root dark defaults + [data-theme=light] overrides)
Keep intact
- DPR-aware canvas sizing (fitCanvas)
- visibilitychange pause/resume
- prefers-reduced-motion guard
- ring cap splice (rings.length > 80)
- theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)
Known limitations
- No pointer/click interaction — rings only emit on auto-timer
- Background color hardcoded in CSS (#17151a)
- Reduced-motion mode renders a static frame loop (30 draws) rather than a true single static image

- 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.
- 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.
