More Astounding Sandcastles from Sculptor Calvin Seibert

Calvin Seibert just took a ten-day holiday in Hawaii. The good news for us is that we now have a fresh selection of jaw-droppingly amazing sand sculptures to marvel over (we last marvelled here).

The New York-based artist is gaining a bit of a following thanks to his striking geometric designs, and the staggering level of patience it takes to construct them. Sometimes his creations resemble castles, but more often they cross over into a more imaginative realm and we see strangely shaped mountains, mysterious walled cities and futuristic landscapes.

"Building 'sandcastles' is a bit of a test," says Seibert. "Nature will always be against you and time is always running out ... I rarely start with a plan, just a vague notion of trying to do something different each time.

"When they are successful they don't feel contained or finished. They become organic machines that might grow and expand. I am always adding just one more bit and if time allowed I wouldn't stop."
