Imagine a museum or gallery with a serene and contemplative atmosphere, housing a sculpture exhibit. central to the display is a colossal tombstone, symbolizing the extinction of humanity, with stainless steel sculptures of a pigeon and a cat perched atop. the sculptures are crafted with such lifelike detail that they seem almost ready to leap from their stone perches. the tombstone is an intricate work of art, its size and design invoking the lost grandeur of bygone civilizations. natural light filters through the gallery windows, casting a gentle glow on the sculptures and creating a solemn ambiance. the room around the exhibit is sparse, with other sculptures in the background, encouraging a focus on this poignant centerpiece.
