For more information about BarCamp, head to the website. Also, here's a description:
BarCampNYC3 is an ad-hoc gathering born from the desire for people to share and learn in an open environment. It is an intense event with discussions, demos, and interaction from attendees. The event doesn't cost any money, but there is a price: all attendees must give a demo, a session, or help with one.
