Last night I was telling a friend over dinner about the wonderful website TEDTalks. TED (Technology, Entertainment, Design) is a conference. TEDTalks shares the best ideas from TED with the world, for free. The site speaks of;

"trusted voices and convention-breaking mavericks, icons and geniuses, all giving the talk of their lives in 18 minutes."

It is often fascinating stuff. You can view TEDTalks at the site, on YouTube or by free subscription on iTunes).

Here is a marvellous, humorous, terrifying example to set your imaginations racing.
