Thanks Dan, that is just what I was looking for.
Kim, I ned it to flow over a flat plane and then apply that slice of the 3D
procedural to my object with a specifiv UV projection so the fractal follows
curves. I started animating the spatial support but obviously the procedural
flows through the object instead of along the surface, so Dans suggestion
fits the bill here. Thanks both for your input!
