This is a homeless young man who is walking round the coast of mainland UK. He's currently covered 1,700 miles since last year, about one quarter of the way. He supports himself by making art displays from pebbles, en route and receiving donations. His intention is to write a book about the journey when it is completed.
The current work is about a week from completion. He has so far, made two seagulls, and has two more to make, then he intends to add a sun and sunbeams to surround them.
