Distort > Ripple effect
The Ripple effect creates the appearance of ripples in a specified layer, moving away from a center point in concentric circles. The effect is similar to dropping a stone in a pond. You can also specify that ripples move toward the center point.
Animate ripples at a constant speed using the Wave Speed control. This control does not require keyframes for animation. Animate ripples at varying speeds by creating keyframes for the Ripple Phase control.
