Open on a wide establishing shot of a cozy sunlit workshop where a towering wooden Rube Goldberg machine fills the frame, its tracks and ramps glowing faintly. A hatch releases and a cascade of luminous glass marbles rolls onto the track, the camera swooping in to chase them through corkscrew spirals and brass funnels. Each marble's momentum triggers tiny wooden hammers and spinning brass gears in perfect chain-reaction rhythm, macro close-ups freezing the instant of glass-on-glass collision as light refracts into rainbow prisms. The marbles plummet through a domino waterfall, spiral a final helix, and land in a velvet-lined cup that tips to restart the loop seamlessly. Warm tungsten lighting bathes every surface, dust motes glitter in the light beams, the mood is playful and deeply satisfying, rendered in handcrafted stop-motion animation style, photorealistic materials, 24fps.
