If you live in San Francisco, California, then you may be lucky enough to come across the art of Andres Amador. He doesn’t paint or sculpt. He prefers a medium that is temporary but absolutely beautiful: a sandy beach at low tide. He uses a rake to create works of art that can be bigger than 100,000 sq. ft. He spends hours creating these intricate masterpieces, knowing that the tide will soon come in and wash away his work forever.
