Umberlight · Shadow Theatre
Umberlight: an original shadow-art theatre. Move and rotate raised brass, enamel and wooden objects; move the lamp to make their projected shadows fill six illustrated silhouette stories. Forgiving overlap scoring, optional gold outlines, actionable nudges, undo/reset, keyboard/pointer/touch controls and a device-local collection. Four GPT-generated paper and material textures are integrated into the draggable pieces and shadow cards, bundled locally. Original MIT code and authored puzzles; simplified point-light projection, not a scientific model. Inspired by Cornell June 2026 ShadowDraw research.

Static local assets; no backend, login, secrets, runtime external assets, popups or downloads.
