With less than 18 minutes in which to crystallize and share their ideas for reshaping the world as we know it, presenters at TEDxSMU, held October 9-10 in the Owen Arts Center, offered their answers to the question "What will change everything?"

TED (short for Technology, Entertainment, Design) is a New York-based nonprofit group that hosts annual conferences in California and England and helps sponsor independent, smaller-scale spin-off events like TEDxSMU. The group is devoted to what it calls "ideas worth spreading."

Speakers at TEDxSMU ranged from SMU students to a Malawian hero who learned on his own how to bring fresh water to his village using only salvaged items from a junkyard. The wildly successful event concluded with a performance by the orchestral rock band Polyphonic Spree.
