This looks like an interesting project, but I don't see how it can teach kids how to program. I clicked on the lesson 1 screencast and saw that, even before trying to run a single line of code, it dived into importing 2 modules, subclassing and defining 3 methods, and running a GUI. It's hard to grock inheritance if you haven't been introduced to variables and operators. If you actually want to teach kids programming in a way they'll understand, I recommend Zed Shaw's book Learning Python the Hard Way (http://learnpythonthehardway.org/index).
