Hello,
since this is my first post here, wanted to say hi 
I’ve been reading these forums for a while now and finally decide to post something.
Since I’ve played with Terrain recently I decided to try and write some random terrain generators. I was looking in the web for a decent algorithm for the beginning and found this here:
http://www.gameprogrammer.com/fractal.html#heightmaps
So I thought I should give it a try and I added the algorithm to jMonkey, here are some results:
The splat texture mapping is pretty crappy though 
Overall the terrain isn’t very useful if you take it as whole, but it might be able to build some decent looking mountains if you use the generator for maybe a part of the terrain grid.
Here is the class, it extends from AbstractHeightMap, so very easy to use.
Just make a size power of 2 and call the load method.
Feel free to use it for what ever you like.
