I have found the wallpaper after about 25 minutes of wading through posts :P
It WAS Soko and it was this one. http://i.imgur.com/2ciTo.jpg
i'd love to have all 4 together in one if possible, but i can certainly use one of a single Celestial in the meantime. I'll also go ahead and stick the link to the Aspect wallpaper into my wallpaper post for easy reference.
