BIL is a fringe unconference that grew out of people trying to gatecrash TED conferences. BIL UK 2010 is scheduled to be held at Oxford on the weekend after TED, thereby giving some people the opportunity to sneak into TED Global anyway. There are also BIL conferences scheduled in the US for 2010.

How much science will there be? Judging by the videos on the BIL website, quite a lot, but as always it will depend on you, the organisers and whoever else turns up. "BIL is an ad-hoc conference for people changing the world in big ways. It's a place for passionate people to come together to energize, brainstorm, and take action." BILLIANT!
