Oops... the previous definition just created the distortion in the z axis, here's an updated definition that creates the distortion perpendicular to the surface. http://grasshopper3d.googlegroups.com/web/surfacedisplacementdef2.jpg
btw, you can't see the back side of the surface on the previous image because o forgot to make the material 2 sided.
