If you're jonesing for a beach day, look no further than than sculptor Calvin Seibert's Flickr account. His collection of impressive sandcastles will wow anyone, whether you're a fan of Brutalism or not.
Far from your typical turreted castle, the modern geometric structures take on shapes you don't often see made out of sand. Check out what Seibert has to say about his creations:
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.
