American artist Kim Brandell is building the world's largest underwater city off the coast of florida. It is Atlantis with a novel twist - as futuristic design meets ancient Rome, complete with artwork and statues from a multitude of eras. Plans are to make the underwater city, dubbed Neptune, a top class dive site, an underwater cemetery and a new habitat for fish. If the project succeeds, both the ecosystem and the local economy may profit. This is art with an ecological and commercial angle.
