It overlays a sine oscillation perpendicular to each particle's travel direction — producing bobbing, bubble-like wobble along the stream. ![Image: 002767.jpg](https://help.maxon.net/c4d/en-us/Content/Resources/Images/002767.jpg) This Node will superimpose a sine wave function on the movement of the particles. The particles will thus be moved up and down perpendicular to their direction of travel.
