Let's build a machine from stones and string. A wooden frame and metal skin. We'll have to be careful to know what we're doing. Where do we put the candles? Not in the eyes, of course, they can't let the light in. No, the eyes must be mirrors, and the face must have a brushed steel complexion. We can give it a heart of steam, trapped in a glass prism. Pyramids never grow cold.

Do we want it to walk? I don't think so - it might walk away and then we'd have to build another. And if it could speak, what would it tell us? Only what we already know, so we don't need a mouth. The steam stays trapped in the prism, see? It drives the walls outward so the body stays in place like this. Then we drape string all over itlike hair, and throw the rocks away.
