A perfect entry for the beach weather at the end of August: Giant Disney Sand Sculptures (though ironically, because they are in Australia, the pictures were taken seven months ago!). I don’t get it though, how these sculptures hold together. They must be using a different kind of sand (and a different kind of sculptor!) than I use.
A little digging (ha!) found this page in the Google cache, apparently from the site of the people who did the sculptures: Sand Sculpting Australia: About Sand Sculpting. It explains more about the materials and process.
