From the Storymaking Seminar, we know that metaphors spring from the archetype. So just as Obi-Wan Kenobi is a metaphor of the father-figure archetype, the iPod is a metaphor of the magic-stick archetype.
How do you make a metaphor relevant? By using creativity's tools -- multiply, magnify, minimize, and combine elements until your image is captivating. Perhaps the iPod will become the ultimate magic device when wireless is added -- and songs are waved from one magical device to another.
