Ribbons is a study of light and it’s subsurface properties, how much light is reflected or absorbed by an object. Ribbons tests the phasing properties of the shader as an object is passed through a strong light source. This can be seen in the color shifting of the ribbons as they rise and lower away from the light source. A true proof of concept that geometry nodes can gain the unique shader properties, making an essential time saving maneuver available for larger future scenes with scattering systems (ex forests with trees, rainforests with unique flowers, bubbles on the inside of a bottle).
