Strong rule: style --- Realistic 3D animation ---. The skeleton scientist stands before a smoking clay furnace, using a primitive stone hammer to adjust the structure. He then holds a clay bowl containing glowing orange molten copper, carefully pouring it into a rectangular stone mold on the ground. A crowd of amazed cavemen stands behind him, watching the process.

He wears a rumpled white button-down short-sleeved shirt, khaki cargo shorts, and bright green foam clogs (Crocs). He has a simple rope belt around his waist. The visual style is hyper-realistic 3D rendering with detailed bone textures and realistic fabric physics. He often has a determined or frustrated expression.
- Cavemen: Muscular men and women with long, unkempt dark hair and tanned skin. They are dressed in primitive animal skins and furs. Some carry stone tools or sit around campfires. Their expressions range from curiosity to awe as they watch the scientist work. Realistic 3D character models.
