Yeah, I think we're just talking about different points along the journey.
I'm fine with Blueprint and/or Cookie Cutter at first, as the predominant
metaphor, and not too much code.
But then in my code school boot camp model they might have 12 weeks x 40
hours to learn all this JavaScript -> Other Language -> Python ->
JavaScript (they go round and round in a spiral in this curriculum).
So down the road a ways, when it's important to understand more of the
Python grammar, I might move away from Blueprint and Cookie Cutter to
MotherShip and AmusementPark.

I like your relating programming to processing video.
I'm working to forge that connection more explicitly myself. The idea of
"frames" (as in time frames, frames of file, intervals of action) figures
in.
