They do some truly magnivficant sand "castle" structure art work.
I saw a show on the tube some weeks ago, they had a competition, if you were drawn the unlucky one, they blew your in progress creation up with the charges planted under it before you started, then you got to start over again. They had a special prize for the best "come back" sculpture, interesting, but not sure I would want to invest that work to watch it get blown up before it was even finished. End of the competition, the all got blown up, rather dramatic,,,
