      "Whirl and Pinch" distorts your image in a concentric way.

56
        <p>
 
57
      "Whirl" distorts the image much like the little whirlpool that
 
58
      appears when you empty your bath.

        <p>
 
61
      "Pinch" can be compared to applying your image to a soft rubber
 
62
      surface and squeezing the edges or corners. If the Pinch amount
 
63
      slider is set to a negative value, it will look as if someone
 
64
      tried to push a round object up toward you from behind the
 
65
      rubber skin. If the Pinch amount is set to a positive value, it
 
66
      looks like someone is dragging or sucking on the surface from
 
67
      behind, and away from you.
