If you've never heard of it yet, WorldMachine is a tool for the creation of 3D terrain with realistic geological effects utilizing block schemes and quite a number of math functions.

I've been working a lot with it lately, and I find this piece of software fascinatingly versatile and flexible. I am yet to try and use it for 2D-mapping, which just has to be possible, since it's allows to export both heightmaps and splatmaps.

And here comes the question: would anyone be interested in a basic tutorial, explaining the options and benefits of using this tool?
