2x2 网格，对历史上 4 台标志性大型机器执行此操作，16:9 画幅比<canvas_base> 一块巨大、布满灰尘、板岩绿色的大学黑板。上面覆盖着密集的、由 AI 推断的、高度准确的博士级微积分与物理公式，以及与 [$scientific_machine] 相关的粗略粉笔图示。 </canvas_base> <physical_manifestation> - 放在黑板底部木质粉笔托上的，是实体的、现实世界中的 3D [$scientific_machine]。 - 比例：它体量巨大，向镜头突出。 - 材质：厚重铁材、发光真空管、滴答作响的铜制齿轮。 - 交互：黑板上的粉笔线条与 3D 机器在物理上相连。粉状粉笔灰落在机器抛光金属表面上。 </physical_manifestation> <lighting> 刺眼的头顶荧光讲堂照明，从 3D 机器直接投下深重阴影到其后方平坦的黑板上。 </lighting>
2x2 grid, do this for 4 iconic large machines in history, 16:9 AR<canvas_base> A massive, dusty, slate-green university chalkboard. Covered in dense, AI-inferred, highly accurate PhD-level calculus, physics formulas, and rough chalk diagrams related to [$scientific_machine]. </canvas_base> <physical_manifestation> - Resting on the wooden chalk-ledge at the bottom of the board is the physical, real-world 3D [$scientific_machine]. - Scale: It is massive, jutting out toward the camera. - Materiality: Heavy iron, glowing vacuum tubes, ticking copper gears. - Interaction: The chalk lines on the board physically connect to the 3D machine. Powdery chalk dust has fallen onto the polished metal of the machine. </physical_manifestation> <lighting> Harsh overhead fluorescent lecture-hall lighting, casting a deep, heavy shadow from the 3D machine directly onto the flat chalkboard behind it. </lighting>
