Cujoe, one thing that's helped me evolve in the terrain editor is using photoshop filters, and especiall KPT 3, but even pathetic filters are pretty cool for coming up with decent effects... So try making a terrain, then running some math on it, it produces some wild effects....! Here's a little image I was working on, made mostly from the Spheroid designer from my old KPT 3 filters for Photoshop...!
