The Swing protocol is a composition generator that is set to generate both bold and elegant compositions. It works on a 3×2 grid where 7 different lines and an empty shape are randomly placed on the grid on 2 layers. The background is divided into 3 rows or 2 columns that can be filled with 9 different colors or stripes with different coefficients. The paper and the margin can be filled with 6 different colors. The protocol is finely tuned so that the interaction between all the elements always delivers a swinging composition.
