Sometimes, walking on the beach, we come across intriguing shapes in sand, little tubes made of sand and squeezed out from little holes that are home now to little sand crabs. While they are drilling for their shelters, they also eject sand in a form of long tubes that are becoming astonishing sculptures. Sand crabs, artists, without any school are creating modern artistic masterpieces.

Question is- do those shapes have any meaning? Are they some form of letters or symbols? Messages? Or they are just an instinctive urge to create something beautiful?
