Treanor produced his sand murals by sketching designs on paper before using a rake to recreate the design on a beach.[7] The work would then remain on the beach until washed away by the tide.[3] As a result of their innately fleeting nature and circular forms, Treanor's sand murals have been compared to crop circles.[4][5]
Marc had a son and a daughter and had begun doing sand art to entertain them at the beach. This turned in to a full career, working with a variety of organisations, charities and schools throughout Wales. [2]
