I worked with Jack Nitzsche for 'One Flew Over the Cuckoo's Nest,' and we'd booked a symphony orchestra. He dismissed them and came with a little man who poured water into glasses of different sizes to make a glass harmonica. And most of the music for the film was that - with some Indian flutes and some drums.

I learned that the first technology appeared in the form of stone tools, 2.6 million years ago. First entertainment comes evidence from flutes that are 35,000 years old. And evidence for first design comes 75,000 years old - beads. And you can do the same with your genes and track them back in time.
