San Francisco-area based landscape artist and explorer Andres Amador creates incredible large-scale sand drawings using only a rake and some help from volunteers.

“My dream is to do my artwork in locations around the world and to bring more people into the creative act with me,” says the artist.

It’s amazing how many hours are spent creating something so large yet absolutely impermanent as these beach drawings. Amador is also doing beach painting workshops, and according to his website the artist and his pupils have only 2 hours to do their thing before the tide returns.
