When you learn to read and write, it opens up opportunities for you to learn so many other things. When you learn to read, you can then read to learn. And it's the same thing with coding. If you learn to code, you can code to learn. Now some of the things you can learn are sort of obvious. You learn more about how computers work.

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.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
