Why we chose this prompt: Two motions in opposite directions in one shot. The escalator rises while the ball bounces down against it, so the model has to keep both going without one dragging the other along.
A fixed shot of an empty upward-moving escalator. A single red rubber ball bounces down the escalator steps from top to bottom, against the direction of the escalator's movement, and exits the frame at the bottom. No people, no cuts.
