Landscape artist Andreas Amador employs San Francisco's beaches as a canvas for his artistic vision -- creating and photographing large-scale organic designs, like a gigantic zen garden.
You can see more of his work on his website and buy prints and postcards as well. He'll even carve a marriage proposal into the sands of Ocean Beach that can be read from the cliffs above if you want. [Colossal]
See below for more photos and an interview Andreas did with the Canadian Discovery Channel.
