World Cup 2010 interactive - England v Germany - Guardian

Everyone's favourite was our animation of Twitter activity, a fast motion replay of each game in the tournament through the medium of flying balls. Having hatched the plan whilst away on holiday, I was lucky that a host of talented people came together to get things built under real time pressure. You can read the full write up of how we built it on our Inside Guardian blog.

UPDATE:
This piece has featured all over the web since launching, not least Google Creative Lab's round up of the web's most “interesting” things. Perhaps most rewarding was seeing it recognised at the Malofiej 19 awards (official site).
