The BT Tower put on an amazing light show and now has europe's biggest LED display, this has been erected to celebrate the fact that there's just 1000 days to go before the capital plays host to the 2012 olympics.
Speaking about the installation, Sir Michael Rake, BT Chairman, said: "As one of the most iconic and well-known landmarks in London, it's only fitting that the BT Tower is used to generate pride and excitement among Londoners today – 1,000 days to the start of the London 2012 Olympic Games.
"We're extremely proud that the Tower will be playing such an essential role in informing and engaging people across the capital."
In keeping with the Olympics theme, it was a 'marathon' effort installing the display, which weighs around 3.6 tonnes.

According to BT it took 2,700 separate trips in the lift to transport materials to the top of the tower, over seven miles of scaffolding and 2.5 miles of power, lighting and electrical cables to power the thing.

And there were a total of 114 construction workers and engineers who worked on the project – food for thought the next time you look up at the display, which will reside between the BT Tower's 36 and 37th floors until the Olympics take place.
