Circles in the sand

Kantiang beach looks like a picture board.

There are tiny little crabs that form little balls of sand and push them out of their holes as they dig deeper. Once they pop the ball out of the hole they carry it to a strategic place to form the most amazing circular patterns all over the beach.

You are almost too sorry to step anywhere as the crab would then have to start all over to complete his masterpiece.

Then the tides pic up and gradually all the patterns disappear...

A few hours later the beach are full of new artworks.
