Justice are running a great competition. All you have to do is create your own video cover of a track from 'Audio, Video, Disco.' and the winners get to come celebrate New Year's Eve in Australia and see their first new show.
Upload your own video cover on their channel: www.youtube.com/etjusticepourtous/
Be quick as the contest deadline is 12 December 2011. Here's a selection of some of the best ones so far, but you can see them all on the youtube page.
