Distort an image by moving the pixels according to changes of intensity in the mask. The pixels are moved by a distance proportional to the amount of change. The effect causes the image to appear as though seen through a piece of glass whose thickness varies in relation to the mask value. The best effects are achieved by using a soft-edged mask.
