'Glastonbury for geeks' kicks off
Technology fans from around the globe have attended the opening ceremony of an event billed as "Glastonbury for geeks".
The five-day digital festival was kicked off at London's O2 arena by human beatbox extraordinare Beardyman, who gave the crowd a taste of his latest project. It fuses his own brand of music with pioneering technology which has been specially created for him.
Around 5,000 people a day are expected to visit Campus Party, with accommodation provided in the form of a mass of tents which have been lined up in their thousands inside the O2 to create an urban campsite.
Fashion designer Dame Vivienne Westwood will bring a dash of glamour to the event, with speakers set to include Martha Lane Fox, the founder of lastminute.com; Google's Vint Cerf, one of the founding fathers of the internet; and Peter Vesterbacka from the team behind Angry Birds.
Campus Party has become one of the biggest technology festivals in the world, but this is the first time it has come to London.
The show aims to promote digital skills and help entrepreneurs get their ideas off the ground. It will focus on areas including robotics, gaming, social media and astronomy.
