Select terrain based on "roughness"
This macro creates a map of rough terrain in a heightfield.

It works by subtracting a slightly blurred version of a terrain from the original. Pixel values in rough areas change more in the blurred version.

Note that due to the tiny values involved after the subtraction this macro doesn't preview well. You'll need to build the world to see the results, but it's quick to build as it mainly uses just a couple of radius 1 gaussian blurs and some simple combiners etc.
