Serpentine Rl Bundle

Gallery / Serpentine Layout

A true boustrophedon fold of a two-line bundle: the top row flows left to right, drops straight down the right edge, and the return row flows right to left via direction: RL. The bundle stays on the outside of the fold the whole way round (top, right, then bottom) with no crossover, and the descent column aligns under the exit so the drop is a clean U.
