   Tux the Penguin is the official emblem of {Linux}, This eventuated
   after a logo contest in 1996, during which Linus Torvalds endorsed the
   idea of a penguin logo in a couple of famously funny postings. Linus
   explained that he was once bitten by a killer penguin in Australia and
   has felt a special affinity for the species ever since. (Linus has
   since admitted that he was also thinking of Feathers McGraw, the
   evil-genius penguin jewel thief who appeared in a Wallace & Grommit
   feature cartoon, The Wrong Trousers.)

   Larry Ewing designed the official Tux logo. It has proved a wise
   choice, amenable to hundreds of recognizable variations used as
   emblems of Linux-related projects, products, and user groups. In fact,
   Tux has spawned an entire mythology, of which the Gospel According to
   Tux and the mock-epic poem Tuxowolf are among the best-known examples.

   There is a `real' Tux -- a black-footed penguin resident at the
   Bristol Zoo. Several friends of Linux bought a zoo sponsorship for
   Linus as a birthday present in 1996.
