Hi Thomas,

It occurred to me that you might be able to do something like this with that
vine-growing macro.  Have the "vines" grow along the terrain, and then translate
all of the mesh vertices straight down to the bottom of the "vine" and thereby
create a path of erosion.

Maybe change some of the vine-growing rules to instead of being random, seek the
lowest direction to "flow".
