It's hard for me to play around in Gaea without wanting to take the mesh into VUE for a full landscape render. For this scene I used VUE's "spherical landscape" model to (hopefully) more accurately model predawn sunlight on a mountain top. I used some tricks to fake it in "Oasia (Dawn)" :-) This might be another good candidate for the dynamic wallpaper treatment, but I will admit that I haven't seen what it looks like during the day yet...
