Line Integral Convolution is one of the most intuitive data visualization techniques around. It's dropping paint in a river to see how the current is flowing: to visualize a vector field simply take an image and have the vector field smear the colors. The result is a powerful alternative to using arrows or stream lines. And while the intuition is very straightforward, the actual mathematics that power the technique are very complex.
