At OSCON this year, Regina ten Bruggencate and Kim Spiritus gave a talk called How To Get More Kids To Code. I got in late (I was waiting in line to get a free signed copy of The Art of Community by Jono Bacon) so I missed the beginning of this session, but came in as they were demoing Scratch. This is a website where kids can play little games (available in 40 languages) and then click the 'See inside' button to see the code behind the game in a kid friendly way. It’s a great way to get kids to see code and learn not just programming, but the concepts of open source.
