[[File:Animated LIC.svg|thumb|Illustration of how LIC is animated.<br/>Top: normal [[box filter]] (average).<br/>Middle: sinusoidal filter at <math>t</math>.<br/>Bottom: sinusoidal filter at <math>t + \delta t</math>.]]
LIC images can be animated by using a kernel that changes over time. Samples at a constant time from the streamline would still be used, but instead of averaging all pixels in a streamline with a static kernel, a ripple-like kernel constructed from a [[periodic function]] multiplied by a [[Hann function]] acting as a window (in order to prevent artifacts) is used. The periodic function is then shifted along the period to create an animation.
