See rare childhood photos of Facebook CEO Mark Zuckerberg

Zuckerberg began writing software when he was in middle school.  At that time Zuckerberg used to create computer games based on what they drew for him. In an interview, Zuckerberg recalled, "I had a bunch of friends who were artists. They'd come over, draw stuff, and I'd build a game out of it." Zuckerberg was a naturally gifted kid.
