Photorealistic vertical video, 9:16 aspect ratio. A highly detailed, articulated wooden mechanical deer stands on a clean white table in a bright room with a softly blurred workshop background. The deer is crafted from dark, polished walnut wood with clearly visible natural wood grain and subtle brass screw accents at the joints. A human hand enters from the bottom left and points a finger toward a small brass trigger pin beneath the deer’s chest, then smoothly retracts. Immediately after the trigger is activated, the deer begins a smooth, mesmerizing mechanical transformation. The head retracts downward into the neck, the large antlers fold backward, and the articulated legs pivot inward against the body. The ribbed torso segments collapse and rotate in a controlled spiral motion, progressively folding downward. The entire mechanical structure folds tightly into itself, seamlessly transitioning from a detailed deer shape into a compact coil. Finally, all components precisely lock together to form a perfect, smooth wooden sphere with a refined silver-and-brass metal band around its equator. The transformation should feel physically believable, mechanically precise, seamless, and satisfying, with no abrupt cuts or unnatural movements. The camera slowly zooms in and tilts downward slightly to follow the transformation, maintaining sharp focus on the intricate wood texture, brass details, and moving mechanical components while the background remains in soft cinematic bokeh. Natural soft daylight illuminates the scene from the right, creating gentle realistic shadows on the white table.
