G. Augustine Lynas is a renowned sculptor of sand castles and other ephemeral materials. An elaborate sand sculpture. ...

Mr. Lynas has been doing public sculptures for more than 50 years. He designs them spontaneously to be recycled by the tide, encouraging emotional attachment to the disappearing art. When crowds form around his work, he uses the opportunity to remind his audience of the delicate ecology of the oceans and seashores. His works are usually representational, and often combine anatomical forms with architecture and landscape. Some pieces are enormous, some small. A few are dry and low relief, while others are tall and highly detailed. Some employ optical illusions or gravity defying undercuts. His book and film, both titled "Sandsong", have been available through his website of the same name. Lynas has also created a sculpted concrete sand pit in Manhattan's Riverside Park where the sand and its container are similar in color and texture so that children can create sand sculptures which appear to alter the concrete sculptures. Mr. Lynas also works in other ephemeral materials including snow. In 1980 he was invited to build snow sculpture in the athlete's village during the Winter Olympics in Lake Placid, NY. The tide is the regular rising and falling of the oceans surface caused by changes in gravitational forces external to the Earth. ...
