Pointillist

Halftone Bloom

Colored dots bloom radially from center, optically mixing amber, magenta, and teal into a glowing flower. Slow ripple breathes through the dot grid.

When to use it

Dark-mode hero backgrounds, loading screens, or ambient art tiles needing organic radial motion without user interaction.

When not to

Light backgrounds (hardcoded dark navy). Layouts needing legible text overlay — dot field competes with copy.

Working with an AI agent

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

Change the palette to cool blues by replacing PAL values and slow the bloom cycle by setting PERIOD to 8000. 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 (PAL array)
  • bloom cycle duration (PERIOD=5200)
  • mount offset (t0=ts-1500: bloom starts a quarter in)
  • dot count cap (N<110)
  • grid pitch divisor (minSide/9.2)
  • bloom radius fraction (maxR=minSide*0.46)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • IIFE wrapper
  • prefers-reduced-motion static fallback (render(1,0.0))
  • visibilitychange pause/resume
  • DPR-aware canvas sizing
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

  • Background color hardcoded in both CSS and canvas fillRect — must change in two places
  • Dot count capped at 110 regardless of screen size, so large viewports show coarser grid

  • Dot AssembleThousands of colored dots scatter from off-screen and converge to paint a pointillist sunrise scene — hill, sky, and sun disc — then dissolve and loop.
  • Pointillist ShimmerUp to 2600 colored dots optically mix to paint a pointillist riverbank at dusk — sky, water, and grassy bank zones shimmer via per-dot breathing sine waves.
  • Pointillist SunsetA glowing sun sets over shimmering water rendered as colored dot lattices. Sky baked once offscreen; water dots animate with sinusoidal shimmer and sparkle.
  • Stipple Flow108 colored dots drift along a curling sinusoidal flow field, leaving slow translucent trails that paint a sweeping diagonal arc with divisionist…
  • Divisionist Tree2600 orange, blue, and magenta dots form a tree canopy using additive pixel-splat blending; dots vibrate with staggered sine-phase for optical color mixing.
  • Density WaveA density wave sweeps left to right revealing a Divisionist sunset — sky, sun disc, and sea rendered as jittered pigment dots that optically mix at distance.
