Metaballs v3 — Blobs
Filled marching-squares polygons make crisp vector blobs — gradient fills and a glowing additive outline — the lava-lamp metaball look built cell by cell.
Marching squares with the filled inside polygon of every cell, interpolated for a crisp vector edge. Fill solid or with a vertical palette gradient, add a glowing additive outline, and the classic "lava-lamp" metaball look falls out.
