Fitting, isn't it, Sage, that an Oil Rig would be named after a ship in the Evil Galactic Empire. Getting more and more true every day, right? I mean... how long til Iraq is completely wiped out? Afghanistan is pretty much there. Korea soon?
We shall see. But, yes, I fully support the new name for the Oil Rig. Good call

...If for only the trash compactor

... but... does it just dump the trash into the ocean or do you have special waste ships that.... //buying into the article too much

Ha. Anyway...
Ian, weird clip. I can't really figure it out. I usually am very good at figuring out how something was done even if I can't come close myself.
I'm leaning toward it being mostly if not all CG. There's no other way. The camera rotates... can't be much else. The buildings obviously weren't suspended in the air like that.
It might be mostly CG with some real people filmed from underneath on a small set then shrunk and rotated (or filmed with a motion controlled rotating camera).
The one that gets me is the one with the people and everything else just walking like on a treadmill, but in real life. It's not that complex, but looks really cool. Same kinda thing, I suppose.
