Beach Trash Art By David Day August 14, 2016 by Cathy Australian David Day has been making Beach Trash Art. His latest creation is a life-size wave made from flip flops found on the beach. He has made over 40 pieces so far but I love the wave. PHOTO: David Day inside the life-size wave he made from thongs.
