I took lots of photographs and had planned to write a treatise on how it worked, but I quickly got bored with that idea and wrote a scientific fairy tale instead.

You see, my ambition was not to confound the engineering world but simply to create a beautiful piece of art.

The hoop is there to remind us not to jump through it, not to submit to someone else's control.

The dog and the rabbit are telling us not to chase unattainable material goals.

The rabbit is significant in that the handle on the original South Pointing Chariot was carved in the form of a rabbit. Because the handle extended out front it meant that wherever the rabbit went the chariot had to follow.

It inspired all sorts of whims and fancies that I ultimately wove into a fairy tale complete with muse, the earth, the moon, some famous inventors, a dog and a rabbit.

If we listen human instinct actually tells us what we need, but advertising makes us want things we don't need and things we can't have.
