American artist Andres Amador spends hours painstakingly carving giant works of art on Pacific beach shores.
The San Francisco-area landscape artist etches massive sand drawings onto beaches during full moons when his canvas reaches its largest potential.
Using only a rake and often several helpers, the geometric and organic shapes are slowly carved into the sand, often interacting with the physical topography like the stones in a zen garden.
The works exist for only a few moments, just long enough to snap a few photographs before being completely engulfed by the encroaching tide.

He lives in the hollow of the shore of an ocean.
