Where do new ideas came from?

I think ideas came from people's curiousity and imgaination. It comes from when people has a meeting and discuss about the new product. Like the movie E.T. they used their imagination to show how alien look. When they make an idea, they have to make a plan to visualise what the pros see. nd ideas are often born unexpectedly - from complexity, contradiction, and, more than anything else, perspective.
