IMAGE DESCRIPTION:

  This image is an example of how to make seamless liquid textures within
POV-Ray.  The main file has 6 liquid examples, all of which can be animated.
The image for the contest is a composite of two of these textures: ice water
and fresh water.  The others are ocean water, swamp water, blood, and lava.

DESCRIPTION OF HOW THIS IMAGE WAS CREATED:

  POV-Ray's texture patterns, at least the interesting turbulent ones, do not
normally tile.  I have tried many offset duplication methods: all failed.  
Periodic functions do tile well, but they don't make for very nice textures.
As it turned out the secret was to create a pattern function and feed it 
periodic variables.  

  Normally my projects consists of at least 3 files: one for scene layout, one
or more for object definitions, and one for textures.  This one needed only 1 file
for everything, and a fairly small one at that.  A simple file for a simple, but 
interesting, purpose is one interpretation of minimalism.
