I started to notice that after people got onto the sand, marked their towel territory, rubbed on the sun tan lotion, they would all do the same thing. Dig or build. Any age, any sex, any face, I could see the compulsion to dig or build. I started to wonder if there is an innate part of us that has to affect our surroundings. Make our mark. 

One sunny day I decided to put coloured chalks around the steps to see what people would create. Sure enough they drew. To my surprise/disapointment, there was a severe lack of penis's and swear words! 

Later on in rained, and the surroundings got the final say.
