That is so cool looking!
When I was in Florida last March, there was a guy on the beach in front of our condo that was making sand sculptures. He made a mermaid, a couple of dolpins, and a few turtles. It was incredible looking, I wish I had gotten a picture of it. When he was making it, all he used was water(from the ocean) and sand.
Definetly takes a lot of time and patience! I've seen a couch made out of sand before as well, that was weird looking! LOL
Great pictures, thanks for sharing!
