Just started on the actual terrain code a few minutes ago. I was having trouble getting a shader to compile propperly. I didn't realize that the compiler outputted the compiler errors to the debug window, so once I noticed that I got it sorted out - just some small stupid typo that I wasn't seeing.
I'm going to try and get the basic grid rendering before I have to head off for work. Then when I get back I'll start loading heights from an image, and maybe do the normal calculations if everything else goes well.
