The TED Prize event is streaming live now. I watched it last year and it was very moving. I imagine it will be again this year.

About the 2008 TEDPrize

The TED Prize was created as a way of taking the inspiration, ideas and resources generated at TED and using them to make a difference. Winners receive a prize of $100,000 each, and more importantly, a wish. A wish to change the world.

During today's session, webcast live from Monterey, California, the 2008 TEDPrize winners will unveil their wishes for the first time. Prize winners Neil Turok, Dave Eggars and Karen Armstong will be joined by singer-songwriter Vusi Mahlasela.
