Strong rule: style --- 3D Pixar ---. An elderly man with a kind face, twinkling blue eyes behind round silver spectacles, and a thick, well-groomed white beard. He wears a classic brown tweed vest over a crisp white shirt with rolled-up sleeves. His presence is grandfatherly and intellectual. The setting is a cozy, high-tech laboratory filled with books and holographic screens. The art style is polished 3D animation with warm, soft lighting and rich textures.
