On Saturday, there are just 1,000 days to go until the opening ceremony of the London 2012 Olympic Games.

The London Organising Committee of the Olympic Games and Paralympic Games (LOCOG) has released details suggesting more than 5 million people are now “involved” in the Games in one way or other.

So, if you’re reading this, chances are you’re either one of them, or you know someone who is!

Whether it’s the Inspire Programme looking at community projects, the Get Set programme in schools, the Cultural Olympiad, School Sports Week, or your company is working on the Games, it’s becoming clear than 2012 is having quite an impact.

So, tomorrow is time for London to celebrate this involvement in different ways:

• A Games-themed photography exhibition at the National Portrait Gallery, called The Road to 2012, featuring portraits of people working towards the Games
• A spectacular firework display from the BT Tower tomorrow night, including a huge LED banner count-down message on top of the tower. (Watch this from London’s hilltops – Primrose Hill, Parliament Hill or on the BBC Lottery programme from 8.45pm)
• The London 2012 Corgi-made replica London bus goes on sale tomorrow in Hamley’s
• The limited edition adidas t-shirt, with pictures representing all the Olympic sports is available to buy here
• The Royal Mail’s 2012 stamps go on sale

With just 1,000 days to go, all eyes are on the next step: the aquatic centre’s roof is due to be finished before the end of the year…
