It's called "Take the High Ground," and it's done by a fellow out of the UK.
Quite good stuff, actually, and he explains what he's done fairly well, if not exactly step-by-step. But you can easily see how he did things.
I just wish I could duplicate them!
As far as my projects go... real life has intruded pretty heavily in the modeling/terrain making realm, and I've done very little. In fact, nothing at all in weeks.
Maybe I'll put a little time aside this weekend to work on a project or two, inspired by our friend here.
