Suprematist Geometric Forms
Dynamic Composition
Suprematist shapes fly in from edges, hold in a white void, then depart — bars, circles, crosses in black, red, blue, yellow; never repeating.

When to use it
Art/design hero backgrounds, gallery intros, ambient looping displays with a Bauhaus or modernist aesthetic.
When not to
Contexts needing user focus or legible text overlays — constant shape movement competes with reading.
Working with an AI agent
Every component ships agent-ready metadata. An example instruction for this one:
Change PAL.red to '#e05a00' and PAL.blue to '#0077cc', reduce max element count from 14 to 8, and slow spawn interval from 1100ms to 1800ms. 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
- palette colors (PAL object)
- spawn interval (ms=1100)
- max element cap (elems.length>14)
- shape size range (sz)
- element lifetime (life: 5200+random*4200)
- theme tokens (:root dark defaults + [data-theme=light] overrides)
Keep intact
- IIFE wrapper
- prefers-reduced-motion guard and static fallback
- visibilitychange pause/resume
- DPR-aware fitCanvas()
- theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)
Known limitations
- Background color hardcoded in both CSS and canvas fillStyle — must update both to change
- No touch/pointer interactivity by design; purely generative
More Suprematist Geometric Forms components
- The Black Square, BreathingA near-black square barely scales and rotates on a warm white ground; a faint red ghost square offsets behind it. Suprematist stillness in motion.
- Suprematist Drift9 colored bars in black, red, blue, yellow rotate at random angles and drift slowly across a cream field via alternating CSS keyframes.
- The Aviator's FieldSuprematist bars in black, red, blue, and yellow launch diagonally across an off-white field at steady tempo; reduced-motion shows a static arrangement.
- Cross & CircleSuprematist shapes — cross, circle, bar, square — fling in from the nearest edge with cubic ease and a settling wobble, auto-composing on a warm white field.
- Weightless7 Suprematist shapes — squares, circles, bars, crosses in red/blue/yellow/white — orbit and self-spin around an invisible centre on a dark field.
- Red WedgeA bold red CSS triangle slowly sweeps across a cream field past faint black and grey rectangles, evoking Suprematist's Suprematist diagonal.
