Introducing the Elephant Curve

<i>In the book a boa constrictor swallows an elephant. The silhouette of the boa then becomes an elephant curve.</i><p>That doesn't actually happens in the book. The image is just creative drawing by the narrator but most people thinks of it as a hat. Only the Little Prince recognized it immediately as a elephant inside a boa constrictor.

"Though I did not read the book at school"<p>A lot of people actually read that book voluntarily, outside of school :-)

I don't get it? All I see is a hat.

A day's-worth of elphant-curve traffic is done not when there are no more visitors to arrive, but when there are no more visitors to leave.
