not yet! I still haven't started setting that one up. It's on my list though. Although ... it's a big list, haha. and, thanks so much! that's incredibly kind. cheers!   EDIT: using my concrete wall set to test tank wall capability -- was thinking tanks might look awkward with space all along the edges, but it's only a half tile. and actually, the corner piece is only a quarter tile, it just looks like a full tile.   I'm gonna go ahead and get this wall set config
