TUX

 Tux, the penguin, is the generally accepted official logo for the Linux operating system. Linus Torvalds, the creator of Linux, chose Larry Ewing's design simply because he likes penguins. 
It is said that the name Tux was the winning entry in the "Let's Name The Penguin While Linus Is Away Contest" with the "T" standing for Torvalds and the "U" and "X" for Linux.

I am disturbed by the use of TuX in Stuxnet and this Simple Linux Guy (S.M.G) whom I adore. 

His girls are Penny and Gown.

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. 

In video games featuring the character, female counterparts, named Penny and Gown, accompany him. 

The character is used in many other Linux programs and as a general symbol of Linux.
