Mmh, now that you mention it, it looks kind of like that cannon from Hoth...
Not that I had thought it when I have been playing. If I ever saw that first screenshot, from that perspective and angle, I might have, though. In the game those things are so big and "the pipes" facing in odd directions, you can't really tell other than if you're levitating around them or something.
It might even be an intentional reference though. http://www.uesp.net/wiki/Bloodmoon:Bjorn.
