The second TEDx Somerville event was held Sunday, March 30, at Brooklyn Boulders.

The nonprofit TED (Technology, Entertainment, Design) organization started as a four-day conference in California 25 years ago. The annual TED Conference invites the world’s leading thinkers and doers to speak for 18 minutes. TED speakers have included Bill Gates, Al Gore, Jane Goodall, Elizabeth Gilbert, Sir Richard Branson, Nandan Nilekani, Philippe Starck, Ngozi Okonjo-Iweala, Isabel Allende and UK Prime Minister Gordon Brown.

TEDx is a program of local events that bring people together to share a TED-like experience. While the TED Conference provides general guidance for the TEDx program, individual TEDx events are self-organized (the “x” indicates it is an individual event not run by TED).

Sunday’s event, which featured 18 speakers, artist demonstrations and an after party, focused on the theme of movement, whether physical movement through the body, the future of transportation in Somerville and how people will move around the city or the exploration of what moves individuals on a personal level.

The first event was held in 2012. For more, visit the TEDx Somerville page on Facebook.
