NACRE — The Shell Inlay
NACRE is a serene fine-art puzzle: lay iridescent mother-of-pearl shell into black urushi lacquer, partitioning each panel into shell "galaxies" that are perfectly point-symmetric about their pearl seeds — a Tentai Show deduction. Solve a panel and a togidashi polish sweep crosses the surface: the 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.
