Glass Distortion

Simulates an image being deformed as if through a pane of glass. An image well lets you assign an image, movie, or shape to use as the pattern in the glass. Other parameters let you control the scale and amount of distortion.

By default, Glass Distortion behaves as if there were a black image applied to the Distort Input well, which leaves the target layer unchanged.
