British Airways has been inviting UK sports fans to contribute to the Olympic Games using the hashtag #HomeAdvantage on social networks.

The social symphony from the UK flag-carrier derives sounds from tweets, posts and messages on Twitter and Facebook sent in support of GB athletes.

Each user can contribute to the producing of a sound wave, which is getting bigger and louder depending on users’ activity.

People can then filter the symphony by athlete, event or venue and see tweets if they click on the individual particles.

When the activity gets bigger, the symphony goes in a crescendo but when fans are more retrained, the music quietens.

Viewers can see a demographics of the sound wave presented as a scale on the dedicated web site.
