Lightweight animated triangulated backgrounds for the web. Zero dependencies, ~3KB gzip.

fill (default) — filled low-poly triangles with fake directional lighting. A static painting: nothing runs between animations.

lines — the same triangulated mesh drawn as strokes, with a soft light band sweeping diagonally across the edges. Runs a requestAnimationFrame loop (paused automatically when the tab is hidden; stop() pauses it manually).

In lines mode animateIn/animateOut fade the whole layer (per-triangle effects apply to fill mode).
