Have you ever had an imaginary setting (like a set for a sci-fi movie that doesn't exist) sitting vividly in your imagination, and you knew that words alone wouldn't convey what the place looked and sounded like? So, you ended up drawing a picture, just so that your friends could finally say, 'Oh, now I get it! Yeah, that's a lot cooler than what we thought you were talking about!' Best of all, when you're all finished with your illustration, you have a really accurate reminder for yourself, for future reference. This is a drawing of Harrier's lab in the shadow dimension, and this finished illustration came remarkably close to how I originally imagined his lab (and the emotions and moods that it ought to evoke in the audience). If you're wondering, the weretigress on top of his VW is his traveling companion and sounding board. She knows as much about technology, physics, engineering, and dimensional science as he does, possibly more.
