Cool Pic. My Brother-in-law has a trinket that works kind of like a kaleidascope but with different colors of sand in water encased in glass. It is a triangle shape and rotating it makes the sand shift through the water column and changes the view. It is really cool.
Tha only thing I don't like about your photo is all that black sand mixing with white sand. I have some area on the West end of 30-A where there seems to be an unusually high amount of black sand on the beach.
