Zug is the German word for train, but it also translates to 'a force that pulls in a specific direction' which feels very fitting, though it might remain unclear in which direction exactly.

The image is build layering around 9000 transparent strokes grouped so that the resemblance of a passing train is created. Most strokes are blurred, some are repeating.

All editions share the same base color palette. From it three different palettes are derived for the light, medium and dark colors. Press 'c' to get a better idea of how this works.
