Calvin Seibert is a professional sculptor. He enjoys the beaches and he creates these stunning sand sculptures as a memory of the several beautiful beach visits. Children and adults enjoy creating sand castles. Calvin Seibert has levelled up and tested nature  with his modern geometric shaped sand-castles. Building a sandcastle sculpture is quite tricky, since one has to race against nature to complete a structure. Sometimes Calvin just goes with the flow, he doesn' really follow a specific pattern to create his sand castle sculptures.
