You set the scales to 10/100/1, but if you use e.g. 50/50/50 you get smoother warps. Also, if you reduce the variation and the buoyancy to 0, the warps will even be smoother. As you say, possibilities are endless. A good way to see this happen is if you take a simple shape (make a line), set to 'position in terrain', and warp it. Nice tutorial, by the way, many people would perhaps benefit from this.
