me: So then we take the liquified wood pulp, and dry it again, into these thin sheets.
caveman: [confused, but trying to keep up] uh huh.
me: And we take the graphite stick - it doesn't need to be wrapped in wood like this, but we like making them this way so you don't get graphite on your hands. And that's what we draw with.
caveman: [eyes lighting up] Oohhh so you use the wood pulp sheets to paint on them, like hides?
me: Exactly! And now, you could use this method to draw anything you can visualise with your mind's eye, but for the sake of this demonstration, let's draw a vision of a woman with features of an animal whose powers and traits she represents, and a figure that is stylised and exaggerated beyond what nature really allows.
caveman: As wide as she is tall, with tits to match?
me: Exactly.
caveman: This is the only sensible use of this technology.
