This is a tessellation of sharks which Bruce Bilney and I have been taking turns improving over the last year or thereabouts. The original version contained waaay too much space between the sharks. Space, or "gaps", are a no-no in tessellation art: everything should fit together seamlessly without gaps nor overlaps.
The name "Sharks Cove" is also a place-name. It's a popular but sharkless SCUBA diving point near my house, here in Hawaii.
