The Amazing LHC at CERN
Use the Force, Luke!
View of the ATLAS detector during July 2007 (Claudia Marcelloni, © CERN)
"This is not only the largest particle accelerator ever built, it's the largest ... anything ... ever built ...". Besides creating mini Big-Bangs, deadly strangelets and micro-black-holes, the LHC also has things like a "Time Projection Chamber"!?! Say ... what exactly does that do? :) In any case it's amazing just to look at. It's all very sciencefictiony.
Via "The Big Picture" from the Boson Globe, where they have many quality pictures of it (besides the LHC, it also hosts many other stunning photos).
Some Info Links:
public.web.cern.ch
lhc.web.cern.ch
The LHC on the BBC
Einstein Papers
Concerns
PS) And just to show that we humans don't lack a sense of humour, there is also a hilarious article at Cracked magazine, in which the LHC features prominently, all about experiments that are likely to destroy the world.
And of course you just can't have doomsday without some kind of attempt at a soundtrack:

The Hydroptere again ...
... as one fine day in 2007 ... it casually breaks its first world speed record ... to then dominate sailing for the decade to come.

Musica Universalis
Musica Universalis (the movements of the celestial bodies as music)
Kepler wrote:
"The heavenly motions ... are a continuous song for several voices, perceived not by the ear but by the intellect, a figured music which sets landmarks in the immeasurable flow of time."
It is however possible to translate that which Kepler saw as only perceivable by the intellect to also be perceivable by the ear.
Whenever a soundwave is doubled or halved in frequency, it retains the 'flavour' of the original pitch. This can be applied to any periodic cycle, including the orbits of the planets (method explained:
http://homepages.tesco.net/gregskius/oe.html).
These are the duration in seconds of our star’s planets (and Pluto):
Mercury: 0.453028141, 0.906056282, 1.812112564, 3.624225128, 7.248450256, 14.49690051

In 2006, Greg Fox took the above orbital periods and divided them until their frequencies fell within the human acoustic range. This gave him six octaves of "planetary notes" for each planet. He called the resulting “music”: “Carmen of the Spheres”. It can be heard and downloaded at:

Thanks to Alcibiades for that one!
