Media absorption made the difference between "water" and "ocean." A high
dispersion_samples was absolutely necessary to prevent an ugly, disjointed
appearance to the serendipitous rainbow on the 2nd spire from the left.
Radiosity was essential for preventing that "Look at me! I'm RAY-TRACED!" look.
Roll all of them together and you get...
