Throughout history, the evolution of art can be traced through the works of visionary artists who pioneered a new form of artistic expression.
One such artist, who is busy livening up the beaches around San Francisco, is Andres Amador, beach artist extraordinaire.
Andres, has been creating a series of new designs, spending hours painstakingly carving giant doodles on the beach, some spanning a massive 300 by 500 foot.
He uses Google Earth to pick out the best beaches for his designs. He then patiently waits for a full moon to make sure tides are low enough for him to complete his design before it is washed away by the sea.
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.
Andres has also collaborated on a number of killer marriage proposals, the question popped as part of his elaborate drawings viewable from an elevated distance.
He said: ‘One day while on the beach and was explaining aspects of geometry to a friend, creating circles and triangles on the beach.
‘It was then that it occurred to me that I could do these designs in the sand, that their size could be virtually unlimited and that the most perfect beach to work on was near to my home in San Francisco.
‘My designs are inspired by patterns in nature, such as ripples in water, cracks in mud.
