253    The shape of a torn edge is tied to its location on
254    the target document, creating a cue of scale of the torn-off
255    piece on the screen.
256    Furthermore, the varying shapes of the edges
257    help the user distinguish between targets torn off
258    of different places.

260  JVK  When a link is followed, the torn shape of the target buoy
261    animates to the full shape of the document, as if larger and
