More than 3,000 people have volunteered to translate TEDTalks into (at last count) 77 languages. Above are some of those dedicated volunteers, on the plaza of the Ashmolean Museum after Session 9 for a breezy group portrait.

In the year since the program began, there have been almost 60 TEDx events worldwide, from Washington, DC, to Kibera, to Beijing. Find out more about TEDx — including events near you:
