Artist Calvin Seibert (previously) spent part of the summer on Rockaway Beach in Queens where he made quick work of erecting several of his trademark geometric sandcastles that we’ve admired for years here on Colossal. Seibert is a professional sculptor who relishes the challenge of building these temporary sand structures inspired by brutalist architecture and aspects of modernism. He shares about his process:

Building “sandcastles” is a bit of a test. Nature will always be against you and time is always running out. Having to think fast and to bring it all together in the end is what I like about it. I rarely start with a plan, just a vague notion of trying to do something different each time. Once I begin building and forms take shape I can start to see where things are going and either follow that road or attempt to contradict it with something unexpected. In my mind they are always mash-ups of influences and ideas. I see a castle, a fishing village, a modernist sculpture, a stage set for the oscars all at once. 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.

Seen here are a number of his designs from the last year but you can explore hundreds more over on Flickr.
