The hardware commissioning of the Large Hadron Collider (LHC) can be monitored on this website. Things are coming together fairly quickly now. The first particle beam injections took place on August 8th. On September 10th, the first full beam circulation will occur. On October 21st, the first high energy collissions should occur.
[Update: 24 September 2008] Because of an overheated connection which caused a helium leak, it looks like the LHC will be out of commission until April 2009, at least. That is fairly understandable given the complexity of the machine, but it is still disappointing that we will have longer to wait for results.
