42

A row of white rectangular cards with black geometric patterns and the number "42" printed on them are arranged in a line on a flat surface. The cards are set up to fall in a domino effect, with the first card tipping forward and initiating a chain reaction that causes each subsequent card to topple in sequence. The cards fall from a standing position to a horizontal one, moving from left to right across the frame. The setting is a simple indoor environment with a plain wall and a light-colored surface.
