For those with 17 minutes spare, here is a 171 MB, 17 minute long mpeg file animation of how the thing was put together, with some fairly soothing Leftfield track in the background.

I love the "DHARMA" style beginning to the video!
You can see towards the end of the video just how much shielding has to fold around the beam pipe to protect the nearby LHC magnets from bits of beam that will spray forwards during beam collisions. This rotating shielding is coloured orange in my videos of the real thing, and wraps around the green pointy bit in the 3rd video. The LHC beam is powerful enough to make a real mess of concrete, so this shielding is several tens of tons of steel.
