Wraped not warped ;)
Anyhow I am attempting to create a repeatable image IE it repeats 
horizontally (vertical isn't a problem). I know certain types of textures 
repeat themselves some do not or.  I suppose what I'm asking, is there a 
way to make a random looking repeating texture? (that's a mouth full).

sure:

-begin code-

#declare Texture=
texture {
    [some very interesting texture stuff goes here]
}

#declare Tileable_Texture=
texture {
    gradient x
    texture_map {
        [0 Texture]
        [1 Texture translate x]
    }
}
-end code-

now Tileable_Texture is a texture that is tileable between x=0 and x=1.

cu!

You can try Chris Colefax' tile generator macro:
