Invisibility has always tantalized mankind, simply because they have such difficulty being anything but visible. They smell, they cannot flatten themselves out of sight like prowling leopards, they are slow moving compared to scampering mice, and they cannot soar above out of sight like a condor. Being invisible seems to offer so many advantages, from escaping notice to being able to snoop, that it has been a favorite focus of much fiction, including the book The Findhorn Garden.
