Alright. Found myself playing again today with a direct matrix transform 
  against yuqk's updated wrinkle pattern. The attached animation uses

             matrix <
                 1.0, (frame_number-1)/60, 0.0,
                -(frame_number-1)/60, 1.0, 0.0,
                 0.0, 0.0, 1.0,
                 (frame_number-1)/57, (frame_number-1)/37, 0.0>
