I am working on one, but it is even less finished than the one by Samuel 
T. And besides, it focuses more on the syntax and what isosurfaces are, 
rather than how to predict what they will do.
I dont know of any others.

"pattern" is designed for the height field object, it really isn't very 
useful for anything else, and can't be used as a normal(there really 
isn't any reason to do so).
"function" can be used as a pattern, like this:
pigment {function {abs(sin(sqr(x*0.1)))}}
   color_map {
      [0 color Black]
      [1 color White]
   }
}
