A Bug's Life

It's basically a big weekend gathering of people (traditionally computer geek types, but similar events have attracted those with interests in science and medicine etc).

The event is free for all attendees, with funding for venue, food etc being covered by sponsors. Everyone is encouraged to participate in some way, with most choosing to do a talk about something they are interested in.

It's described as an 'unconference' for this reason, there are no traditional 'attendee' and 'speaker' role, as everyone does both. At the beginning of the event sessions are put on the schedule (aka 'the grid') and then people simply pick the talks they wish to attend.

The majority of the events have an overnight component (like a grownup sleepover!). People self-organise a mixture of discussions, play boardgames or BarCamp favourite 'werewolf' or watch DVDs. They can choose to stay all night, camping out on the floor.

BarCamps started in the US, but are now held all over the world. I myself have helped organise the last two events in London, which took place at The Guardian's HQ and IBM on the Southbank respectively.
