Tux
Tux is a penguin character and the official mascot of the Linux kernel. Originally created as an entry to a Linux logo competition, Tux is the most commonly used icon for Linux, although different Linux distributions depict Tux in various styles. The character is used in many other Linux programs and as a general symbol of Linux.
In some video games featuring the character, Tux has a female counterpart named Penny or Gown.
History
Origins
The concept of the Linux mascot being a penguin came from Linus Torvalds, the creator of Linux. Tux was created by Larry Ewing in 1996 after an initial suggestion made by Alan Cox and further refined by Linus Torvalds on the Linux kernel mailing list. Torvalds took his inspiration from an image he found on an FTP site, showing a penguin figurine looking strangely like the Creature Comforts characters made by Nick Park. The first person to call the penguin "Tux" was James Hughes, who said that it stood for "(T)orvalds (U)ni(X)". However, tux is also an abbreviation of tuxedo, the outfit which springs to mind when one sees a penguin.
