Paper Wad
I would use the WAVES.PXP instead of RIPPLE.PXP, also to help wrap it up
into a ball, you might try the Modify\Vertice\Bend or Modify\Object\Bend.
Just be careful that the vertices don't travel through each other during
the Morph back to a flat sheet. You may have to create a few tween morphs
to avoid this.
