The, erm, pillar-ish thingies I made like that because, well... Dirty future walls, how could they lack incredibly odd shapes? 
I was going to add a ton of caution stripes too, to piss off Mike, but he'd break my leetle skull. 
But on a more serious not, I went for depth in the texture, disregarding practical use.
And yeah, it's stone. I made it, left the computer for a while and when I got back I realised that while making it I got kinda lost. I won't be working on it further though, I have other textures to work on.

Thanks for the welcomes.
