"Gravity-defying" beach sculptures made from raw materials there

Sam Bennett makes art out of stones, driftwood and other natural materials found on the beach. It's like Andy Goldsworthy, but fun instead of spooky.
The tides may wash away his work but he says its ephemeral nature is key to why he does it.
'It's there for a moment and gone the next, I'm just moving nature around,' he says of his art.
