SUMINAGASHI

The ancient Japanese art of marbling ink on water, made playable. Drop concentric rings of sumi, indigo and crimson; comb the surface into flowing waves; and draw a stylus through the water to open blossoms — then lift the paper to capture your print. A meditative fine-art puzzle built on a real deterministic marbling engine (every tool is a closed-form fluid transform), so the title screen marbles its own masterpieces. Twelve master prints across three chapters, a koto score, a mounted atelier gallery, and a free studio. Portrait-first, pure JavaScript, no build.
