If you haven't found it yet there is a web site that I am highly recommending to anyone who will listen.
The tag line is "Ideas Worth Spreading" with a subtitle of "Inspired talks by the worlds greatest thinkers and doers."
It is a collection of webcasted talks on virtually every subject you can imagine, by people who are inspired by a passion for what they are doing. It is a great place to pass some time and you will learn cool things.
I hope your enjoy TED. If you do, shoot me an e-mail because I like to hear when I have turned folks onto something very cool. (All create belongs to my co-worker Don who turned me onto TED. It's like crack...for the mind.)
