Where did I get this Wallpaper?

So about 6 months ago I had to reformat my crappy Wintel PC again, and I was out looking for a new desktop. I found this one cool site where one guy made a bunch of designs that all were similar.

I found my favorite and did the left-click set as desktop thingy... now that I want to find out where it first came from I'm totally lost.

My Cache is clear. My History is clear. I can't even get a bead on the original graphic since Windows converted it to a BMP first.

I attached a smaller preview.. If anybody can remember a graphic, I would expect a Mac Person.

Thanks

Anybody? Am I totally lost here?

I refuse to give up on this one.. Somebody out there has seen this picture before. Who?

Indeed, it's not the usual clean and simple desktop that most Mac Users have, but just something about it really intrigued me. The thumbnail doesn't show it very well, but it's a bunch of multicolored "paint" splattered on top of a very detailed two tone ornate building.

I edited the original post's title to specify that I want to know what website these came from. Just to alleviate any confusion.
