Reaction: Imaging Vector Fields using Line Integral Convolution

This paper introduces a new algorithm to use curvilinear filtering techniques to locally blur textures along a vector field. Algorithms which image directional information can have wide applications. This technique can also produce some interesting novel effects.

This paper gives a nice introduction to the domain of directional information. I feel that motion filters are fast catching up due to hardware advancements and this is going to open up new vistas in visualization in the future. It remains to be seen when this actually takes place and how the user experience in visualization will be enhanced at that time.
