Where do Good Ideas Come From?

I just came across this short video previewing Steven Johnson's new book, Where Good Ideas Come From: http://www.amazon.com/gp/mpd/permalink/m3O3C2EO0XITMC. It is very cool - if you like the UPS commercials with the whiteboard guy, you'll love this. But he also raises two great points that come up again and again in my classes - the myth of the brilliant flash of insight, and the need for collaboration and hard work to turn a great idea into a viable business opportunity. I'm looking forward to getting the book in October when it's released.
