As far as I am aware, Kirk's original code can be applied /as is/ to any 
height_field at large. I am applying it without change, only playing 
with the parameters. Is that what you mean?

Can we get a closeup of what the individual water cones and cylinders 
look like? I'm wondering if the result will still look good from a near 
distance.

Are there any free tools that will generate both the eroded terrain 
mesh, as well as a mesh of the water surface? I've messed around with 
World Machine, but it only does the former.

As a free tool, Wilbur does a pretty good job for the terrain 
http://www.fracterra.com/wilbur.html

I do not know of a /free/ tool doing both terrain /and/ water. Otherwise 
there is GeoControl2 (now WorldCreator; 
http://www.cajomi.de/GeoControl/geocontrol.htm offline at the moment) 
and - I think - Leveller that do that I believe 
http://www.daylongraphics.com/products/leveller.php.

 From nearby it does not look too good, I can tell you.

World Creator looks really neat. Too bad my skills suck. Maybe a 
volunteer will appear one day and make some better terrain for my Lego 
project.
