Basically what I am talking about is floating lumps of snow and 
slush...bits of stuff which sheared off when the floes separated and 
bumped into each other. Right now it seems strange that the floes 
separated cleanly, without smaller pieces breaking off.

But that doesn't answer my real question...what "manual changes" 
wouldn't be possible with isosurfaces? Why would CSG be needed with 
isosurfaces, but not with height fields?
