I listen to NPR and they had a relevant show on called "Science Friday". They interviewed an author about the invention of many things through DARPA. It was an introduction to the process of inventing.
I want to encourage all of us to become active in the creation of the things we wish for and want. Inventors and manufacturers need our input. We have clout and power as consumers. They will listen to us if we present the information in a way that they can use it. Here is the link: http://www.sciencefriday.com/program/archives/201001012
I also use a book titled:
"A Whack on the Side of the Head: How You Can Be more Creative" by Roger Von Oech
I found this in a new ventures course at Stanford's B school. It is great fun, too!
