If you haven’t discovered it yet, take a look at http://www.ted.com
There are loads and loads of interesting, educational and entertaining videos of presentations and talks.
Start here. This is a talk by Frans Lanting, a wonderful nature photographer. It’s a slideshow of his own photos that he’s put together and narrates to tell the story of LIFE, of evolution, of how LIFE is about continual becoming (see that “becoming not being……” byline at the top of my blog? You can see why this talk appeals to me).
The photos are just stunning.
Heroes Not Zombies 
Yes, TED is an excellent website. I blogged it too when I discovered it.
