This couple was packing its gear and getting ready to head home after a long day at the beach. I watched and waited as the woman unfolded a large translucent beach towel and began to wrap it around herself. The light passing through the towel, as well as its color and shape, resemble the wings of a butterfly. The diagonal flow of the towel repeats the diagonal struts of the Imperial Beach pier in the background. The rows of horizontal waves echo her outstretched arms as well, while a smattering of bathers link the couple to pier in the background.
