Isle of Wanderers Puzzle

A 3D fantasy scene created in Vue: on a lonely island in the midst of the peaceful sea stands a lamppost with four pale pink glowing lamps. A lone tree with purple-grey leaves, an abandoned little boat, and a passing dolphin are the only other signs of life in this eerie ocean. Not more than one person in five hundred years finds this tiny island. It doesn't stay in one place very long. But anyone who is drawn to these mysterious lanterns, and comes to get a closer look, vanishes into another world, and never comes back. The question is, do they want to?
