Top 10 gadgets, gizmos and hidden technologies behind the London 2012 Olympics

After seven years of planning and preparation, the Olympic Games is all but over. But it has been an enthralling two weeks of fantastic sporting drama, with Great Britain excelling across the board, hauling in over 20 gold medals.

We knew the Games would be special, but not this special, and while we pointed out some of the technologies that would prove key to delivering a successful Games, there have been some plenty of gadgets, gizmos and other unsung technologies that have played their part in delivering the event.

Here, we salute these new technologies and innovations that have played their part in two incredible weeks for the nation. And if you regret that it's all coming to an end, don't worry - the Paralympic Games start in two weeks' time, so there's plenty more to come.

10. The yellow world record line imposed onto the swimming pool

While Britain didn't excel in the pool, many others did, notable Michael Phelps who became the most successful Olympian of all time, reaching 22 medals.

What made the pool events even more fun was that during all the main races, there was a nifty graphic imposed onto the pool showing where the world record pace for the race was so you could see how far ahead or behind those competing were.

This meant that, even if a race was clearly over, there was still the thrill of watching to see if those out front could catch-up or stay ahead of the relentless yellow line indicating world-record pace.
