This skybox started out as just me fooling around in Terragen trying to create a fog-like effect, but after i got that right, i decided to add in the sunset. After i showed some in IRC, it was suggested i make it into a skybox, so here it is. This started out as a wallpaper. You can download the skybox from MediaFire here:
