How to Design a Yogg-Mabial

Bran sends Lewis an email with the promise of a real-life yogg-mabial. This will be a manually controlled vehicle that he will design with his friends and engineers. He's drawn a little picture as well to go along with the story. Do you think I should show you the picture first, or Illustrate? You can describe what's in the picture. We'll put it on somewhere. On the internet, somewhere.
