I thought this might be most appropriate in the art section, so wanted to point this out since I've not seen mention of it for the longest time now.
If you take a look at Ops in DS9, you might notice that the center table the Ops room surrounds has been duplicated and reversed, clipping into itself backwards. This leaves us with two center tables going in both directions from within each other.
I don't know if this is because someone added something like a functional Foundry-usable table but put it the wrong way, or for the last featured episode arc, or such, but I wouldn't mind if someone could take a look at that and disentangle that mess =P
It's bothered me for a while, so decided to just...toss that out there...
