Incendia - This item was created as a background for another image ([link]). In the other image, I blurred it so that the detail didn't stand out too much. But, since it had just nice detail, I thought I'd load it here in Resources/Stock Images for others to use. It's 3072x3072 in full size. Feel free to use it as a background or anything you wish. If you do though, drop me a note so I can see what a *real* artist can do with it.
I find I like this one better than most of the 3-dimensional ones. Purely a personal taste thing.
Is this the one you were referring to that would take several days to render? It's rather trippy.
