I discovered TEDTalks, a remarkable resource for video podcasts of some of the world's most fascinating experts and lecturers in the fields of technology, entertainment, and design, through Linda Jarvin, the Deputy Director, of the CELT and PACE Centers at Tufts University.
She sent me a link to a remarkable video of Hans Rosling, professor of international health at Sweden's world-renowned Karolinska Institute and founder of Gapminder, presentation using the equally remarkable Trendanalyzer software:
Debunking third-world myths with the best stats you’ve ever seen
Rosling "debunks myths about the so-called “developing world” using extraordinary animation software developed by his Gapminder Foundation. The Trendalyzer software (recently acquired by Google) turns complex global trends into lively animations,..Animated bell curves representing national income distribution squish and flatten. In Rosling’s hands, global trends — life expectancy, child mortality, poverty rates — become clear, intuitive and even playful.
Gapminder is "a non-profit venture for development and provision of free software that visualise human development."

Included in the extensive list of videos is Tufts' own Daniel Dennett, University Professor of philosophy.
"Philosopher and scientist Dan Dennett argues that human consciousness and free will are the result of physical processes and are not what we traditionally think they are." TEDTalks has his
Can we know our own minds? presentation and his response to Pastor Rick Warren. For easy access to both videos, go to Dennett's speaker page.
