Here's where technology became my friend: I never could have done that labyrinth without the help of a sign-making friend, Gordy Saunders, and his vinyl plotter. The above is a detail on the hood. Note (if you can, in this horrible photo of mine!) the sharp shadow on the bird at the left. The bird is rounded but her shadow is knife-like. That's in keeping with the idea that the Tree of Life is ultimately the Tree of Death, too, since you can't have one without the other.
