Richard Culatta on education..digital divide (those who use tech to re-imagine learning and those who use tech for traditional learning). Powerful TED Talk.
Storyboard that--looks like a great free online story board. Would work well with graphica, free and educators can set up their private classroom accounts.
I am sure you know about TED videos. This project looks really interesting--you can take videos and add commentary, questions and more for your classes by using videos of dynamic educators. Lots of potential.
