BEIJING, mar. 13 (Xinhuanet) -- When artists see a canvas, most of them want to fill it, even if it's with nothing more than a doodle.

But sand artist Andres Amador works with one of the biggest canvases available, with entire lengths of beaches swallowed up by his art.

Amador has been producing sand art on Ocean Beach in San Francisco for five years and has completed more than 100 pieces.
