I started my career as a journalist, writing about science and technology for 'Business Week' magazine. Then I decided to make a career shift. I went to graduate school in computer science, and I began developing educational technologies - in particular, technologies to engage children in creative learning experiences.

With 'Scratch,' you create computer programs by snapping together graphical programming blocks, much like LEGO bricks, without any of the obscure syntax and punctuation of traditional programming languages. After creating an interactive 'Scratch' project, you can share it on the 'Scratch' website, just as you would share videos on YouTube.

With 'Scratch,' our goal is to allow people to mix together all kinds of media, not just sounds, in creative ways. We want people to start from existing materials - grabbing an image, grabbing some sound, maybe even bits of someone else's program, and then extending them and mixing them to make them their own.

It is only when you watch the dense mass of thousands of ants, crowded together around the Hill, blackening the ground, that you begin to see the whole beast, and now you observe it thinking, planning, calculating. It is an intelligence, a kind of live computer, with crawling bits for its wits.

If I'm serious, yes, I'd like to have done what Shakespeare did... to act and write. You learn so much from acting. One of our great writers, Alan Bennett, does both supremely well. When I write a story, I tend to speak it aloud as I'm writing it.

The leg system of the beach animals works because of a combination of certain lengths of tubes. Because of the proportion of lengths, the animals walk smoothly. You could say that this range of numbers is their genetic code.
