This year's TED (Technology, Entertainment, Design) prize, normally given to an individual, was awarded to an idea dubbed "City 2.0". Ten projects that are improving city life were selected to benefit from the $100,000 (£64,300) prize fund.
Winners include a designer of an open-sourced 'wiki-house'. The first winner, announced at the TEDx summit in the spring, was Ruganzu Bruno who will be using the money to create a play centre, built entirely from plastic water bottles, for children in the slums of Uganda to play and learn.
Four of the winners were announced at TEDGlobal, while the rest to be revealed in the autumn. All of the projects are outlined on the City 2.0 website.
