NACRE

A fine-art raden (mother-of-pearl inlay) puzzle. Lay iridescent shell into black urushi lacquer, partitioning each panel into galaxies that are perfectly point-symmetric about their pearl seeds — a serene Tentai Show deduction. Solve it and a togidashi polish sweep crosses the panel: nacre shimmers, concentric rings radiate from every seed, and the pearls bloom. Twelve uniquely-solvable panels across three lacquer settings, a live arcade demo, and a Cabinet of all you inlay. Portrait-first, pure JavaScript, no build.

KIRIGAMI

The art of the folded, cut paper, made playable. Snip the folded sheet and every cut blooms symmetrically across the creases; match the printed pattern, then watch the waste flutter away to reveal your paper-cut. Built on a real fold-symmetry engine (one snip, mirrored eight ways), so the title screen cuts its own masterpieces and the demo is the regression test. Twelve patterns across three traditions — quarter-fold crests, vermilion cut-pictures, and eight-fold snow flowers — with a koto score, an atelier gallery, and a free studio. Portrait-first, pure JavaScript, no build.

MANDALA (Remix)

The art of the poured sand painting, made playable. Pour coloured sand into the folded wedge and every grain blooms symmetrically across all the petals at once. Match the printed chart, then watch the finished mandala sweep away to the winds — the ritual of impermanence. Built on a real dihedral-symmetry engine (one pour, mirrored up to twenty-four ways), so the title screen paints its own masterworks and the demo is the regression test. Twelve mandalas across three traditions, with a singing-bowl score, a shrine gallery, and a free sand studio. Portrait-first, pure JavaScript, no build.

SHIBORI

The Japanese art of indigo resist-dyeing, made playable. Fold the cloth, clamp the resist over each region, then plunge the whole cloth through the ai vat — deeper with every dip. Clamp on time and a region keeps its shade; miss the moment and the indigo drinks it darker. The fold IS the symmetry, so one clamp blooms a kaleidoscopic pattern across the opened cloth. A real fold-symmetry engine drives it — clamp-then-dip is both demo and regression test. Twelve cloths across three traditions — itajime, kumo, arashi — with a rin-bell score, a cloth gallery, and a free dye studio.

MALAM

The Javanese art of batik, made playable. Draw hot wax to seal a colour, dip the whole cloth into the next dye down a deepening chain, then boil the wax away to reveal a symmetric masterwork veined with crackle. One canting stroke blooms across the wallpaper symmetry, so you wax only a single folded motif. Twelve cloths across three traditions — the kawung palm-sugar grid, the ceplok star medallion, and the graded indigo rain-clouds of Cirebon — scored with a gamelan. The deterministic dye engine is both the attract demo and its own regression test. Portrait-first, pure JS, no build.

CINNABAR

A fine-art Chinese papercut (jianzhi) puzzle. Fold a round sheet of vermilion paper, glide the scissors through the pale grounds and every symmetry fold snips at once, so the red silhouette blooms into a radial window-flower over warm lantern light; pierce the locked hearts with the awl for a flawless cut. Twelve window-flowers across three chapters — Spring Festival hearth-gold, Garden jade, and Celestial moon-silver — with a guzheng score, a papercut gallery of your finished work, and a deterministic engine whose title screen cuts itself. Portrait-first, pure JavaScript, no build.
