Free Software Foundation image of GNU mascot, the gnu animal, and the Linux penguin, Tux from The GNU web site, entitled: The Dynamic Duo: The Gnu and the Penguin in flight. This image depicts the "Dynamic Duo" as superheros, presumably out to spread GNU/Linux. They are shown together to demonstrate the partnership between GNU and Linux required for the complete GNU/Linux operating system, also just called Linux. On their shirts is "GPL", short for GNU General Public License, a popular free software license that GNU/Linux uses.
