excellent ...
the water surface looks much more convincing this time.
AFAIK averaging textures always have the drawback of beeing dammend slow 
as you need at least 10 single textures to surpress banding. Everything 
over 256 would have no noticeable effect in my opinion (at least with 
8bit per channel).
For a given point of the multitextured object POVRay have to run the 
whole tracing routine for each single texture. So by averaging 10 
textures it takes 10 times as long as with a single texture (of cause 
only for the parts in the render where the multitextured object is visible).
