Thanks, yes, especially the second image, which indicates to me that a 
well-behaving substrate does wonders for your little code ;-)

I am afraid that most are Windows only.

There is Wilbur http://www.fracterra.com/software.html which does a very 
good job in tracing river patterns but needs a very noisy substrate to 
do it correctly so additional smoothing is necessary (in Wilbur or - as 
I do - in another application);

Terrabrush http://www.cyberfunks.de/page/terrabrush/index.htm is another 
program I use in between but not so good for erosional processes;

GeoControl (which now seems to be WorldCreator I discover) 
http://www.world-creator.com/ is not a free program. It is the heart of 
my height_field creation modules. It does a fair erosion job. I don't 
know about its latest versions though;

World Machine http://www.world-machine.com/ you already know.

I also grabbed a free copy of Bryce 7 when DAZ made it available a few 
years ago. It can generate some interesting height_fields to serve as 
basis for deeper treatment later.

Interestingly, You can make fascinating height_fields with Apophysis 
flames as basis https://sourceforge.net/projects/apophysis/ . Loaded 
into GeoControl for instance, the pattern is transformed into an 
interesting landscape.
