Hexley

Hexley is the mascot of the open source operating system Darwin, which is the core of Mac OS X.

Character
Hexley is a cartoon platypus that usually wears a cap which resembles a demon's horns, and carries a trident, similar to the BSD Daemon. Hexley was designed and copyrighted by Jon Hooper. Hexley is not affiliated with Apple Computer.

The name was a mistake; the mascot was originally supposed to be named after Thomas Henry Huxley, a 19th century English biologist who was a well-known champion of Charles Darwin's theory of evolution (he was nicknamed "Darwin's bulldog"); however, ignorance led not only to a mistake in Huxley's name but also to a limited understanding of who he was. (The developers apparently thought he was simply Darwin's assistant, when in fact he was a prominent biologist in his own right.) By the time the mistake had been discovered, however, it was deemed too late to change and the incorrect name "Hexley" was kept.

Hexley is one of the playable characters in Super Tux Kart.
