That was my first exposure in sort of being able to communicate with a large audience. It gave me some of the excitement of inventing, being able to move people with projects. That didn’t directly help people in their lives, but that’s the excitement of inventing as opposed to discovering science. Technology builds on science, but it really applies it to a way that moves people, and it is a form of magic. You take just a mundane set of materials, or a mundane set of computer instructions, but in just the right combination it does something that delights people, or maybe even helps them or changes their lives. And that’s the exciting aspect of inventing for me.
