HELIOGRAPH — Signals Across the Iron Valleys
The line went dead at Cold Hollow and you are the new signal-keeper. Turn brass mirrors to walk a beam of sunlight across a hand-drawn valley and into the receiving station — then learn to split white light through a prism into three colours for three valleys, to husband a beam through fog that drains it, and to arrive on the beat while army shutters open and close. Twenty-four stations across five chapters, every one machine-proved solvable, with an honest par and a quiet score of plucked strings and glass bells.

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.
