From what i can tell he may have photo-shopped the pencil drawn images onto the white paper, to make sure that they images really line up... like this goat one... come on... He got the goat to sit still that long... really?
But still a good lesson plan i think! don't you?
Oh yea... Looking at it again he totally photo-shopped his hand and the image over the goat image.... But still good idea!
