All programs are GPL-licensed Free/Open Source software.  They are written in C and use the SDL libraries for graphics and sound.  They are extensively internationalized via GNU gettext, and translations are available in dozens of languages.  The Tux4Kids programs are featured in the educational collections of all major Linux distributions, as well as other free software collections such as MacPorts and the BSD Ports Collection.  Standalone binaries are also released for Windows and OS-X.

Tux4Kids was a mentoring organization in Google Summer of Code in 2008, 2009, and 2010, as well as Google Code-In 2010.  Our programs were also the subject of GSoC projects mentored by other organizations in 2007 and 2011.
