  "brief": "A smooth, brightly colored marble is shown rolling within a concave, funnel-shaped channel. The marble\u2019s movement simulates realistic physics as it descends, first through the curved funnel and then onto a gradually curving diagonal slope at the base. The view follows the marble's trajectory, providing a dynamic, detailed perspective of the rolling path. The scene is entirely self-contained, requiring no interaction from the viewer.",

  "statement": "This sketch simulates a marble rolling down a funnel-shaped channel into a curved slope using basic physics principles. The scene is rendered in 3D with WEBGL, showing the marble's descent through a concave funnel and onto a diagonal slope at the base. The animation runs automatically without user input, demonstrating smooth motion and collision detection. The visual design uses bright colors against a dark background to emphasize the marble's movement and the funnel's structure.",
