My 12 year old son is taking a minecraft mod class -- what I see click is instant-feedback. He loves minecraft, and the instructor showed how writing 1 line of code could make breaking dirt produce diamonds; he was thrilled. He proceeded to change it to produce anything he wanted (eggs, TNT). When the instructor went into classes and constructs and the scaffolding to create a block, he was lost. (But to be honest, so was I !) He loved programming in Scratch -- I know that's simple but it gives you instant feedback to make stuff. I'm thinking about showing him Python -- it's easy, quick feedback, a little less OO dependent.
