Nautilus at the world's end

Færder National Park is a marine national park in Norway encompassing the archipelago of the many small islands of Tjøme and Nøtterøy and the waters as far out to sea as Tristein and Færder lighthouse. the popular park's visitors center is located at World's end which is the main attraction with it's unique nature and history. a sculpture park is spread throughout World's end featuring works of art, nature and history related to the sea and the local geology.

one of the first sculptures visitors coming from the parking area encounter is the enticing Nautilus, a work in copper created by the Norwegian sculptor Kåre Groven

in nature, nautiluses are the only cephalopods (octopus, squid, etc) that have external shells. the unique shells grow as chambered spirals. though increasingly rare in nature with a very limited range, nautiluses are well known as living examples of the fibbonacci sequence because as new shell chambers grow the size of them increases at a constant rate, much like the fibonacci sequence (though the ratio is not exactly the 1.618 that we use in charting).

it's also possible to view the sculpture from the back side, giving structural insight and where the protuberant point of origin is depicted as a silver pearl
