nautilus performance art.

This is a set of musical nautiluses, which I believe originate from the U.K. The website states that "each shell is pulled behind a performer dressed as a fish." I'm not quite sure why said performer wouldn't be dressed as a, well, a nautilus, but oh well. Artistic license.

As an added bonus, each shell plays an ocean soundtrack (if you go to the website you will hear the soothing sound of the ocean which makes you feel like you are at the beach or in the office of a new age masseuse). According to the website, with the five shells projecting ocean music at you, you will experience "total immersion on dry land!"
