This simulator turns art collecting into an explicit, playable model. A rotating market of procedurally generated artworks — each with its own seeded color palette, style and rarity — appears on pedestals in a real 3D gallery. Acquire pieces under a cash budget, either by hand or by letting an auto-curation algorithm rank the market for you along a slider between aesthetic color-harmony fit and expected investment growth. Owned works hang on the gallery wall, where a live coherence score tracks how well their dominant hues agree with classic analogous and complementary color-harmony angles, and collection value compounds every simulated month according to each piece's rarity and the collection's overall coherence, with market volatility injecting realistic noise into that growth.
