Dreaming of a serene beach

More homework for the course on Abstract Photography that I'm doing at the moment. Looking for patterns and if possible breaks in the patterns. Obviously there's no real break in the pattern here, but somehow this image made today appealed most to me.
A close-up/macro of one of my shells, the inside catching some light.
For Tiny Tuesday with thanks to JDO for hosting in September.

Thanks very much for the kind comments and stars for yesterday's succulent in mono :-)
