Television is such an evolving medium. When you're doing a TV show, it's not like you just shoot for six weeks and you're in an editing room with all of your footage. It's like a guitar or a car, you have to fine tune things. You stop doing what's not working, you work on what is working and you add things that do work.

Computers and computing are all around us. Some computing is highly visible, like your laptop. But this is only part of a computing iceberg. A lot more lies hidden below the surface. We don't see and usually don't think about the computers inside appliances, cars, airplanes, cameras, smartphones, GPS navigators and games.
