My friends and I were daytripping in Barwon Heads on a fine but blustery Sunday. We were full from an excellent lunch of fish and chips, had strolled up and down the main street, indulged in a spot of window shopping and made our token girls-day-out trinket purchase. Then the clouds came over and a sudden burst of heavy rain forced us to take shelter. And right there at our feet, the footpath — previously unobtrusive and unworthy of notice — was transformed by the wash of water into a work of art.
