Tux Paint is an easy-to-use drawing program, designed for children ages 3 and up. It offers a simple interface, with large, colorful buttons and sound effects. Even though it is designed for kids, the program is not limited to simple paint operations, but includes a good array of features like paint effects (rainbow, fading, sparkles etc.), auto-fill, text insertion, shapes, image gallery, image stamps and more. The program can either run in normal windowed mode, or full screen. Tux Paint is easy enough to be used by young children, yet provides enough features to keep them using it as they grow older.
Tux Paint is a free, award-winning drawing program for children ages 3 to 12 (for example, preschool and K-6 in the US, key stages 1 & 2 in the UK). It combines an easy-to-use interface, fun sound effects, and an encouraging cartoon mascot who guides children as they use the program.

Tux Paint works on Mac (Intel and PPC), Windows (Windows95 through Vista), Linux and other systems.

Parental and Teacher Controls:
1. Run Tux Paint in full-screen mode, or have it "grab" the mouse pointer, to prevent children from accidentally accessing other programs or files on the desktop.
2. Sound effects can be disabled.
3. The Print and Quit options can be disabled.
4. Alternatively, the Print option can be limited to allow only one print every n minutes.
5. Tux Paint cannot be launched more than once every 30 seconds, to prevent multiple copies from being run accidentally, due to over-eager mouse clicking.
6. The directory/folder where Tux Paint saves files may be changed. This can be used to save pictures in a student's home directory on a network drive or shared drive, rather than locally on one particular workstation.
7. Stamps, starters and brushes are stored using popular open formats (PNG, SVG, Ogg Vorbis, etc.) allowing parents and teachers to create their own content for use at home or in the classroom - even using completely free tools.
8. The "Tux Paint Config." program allows parents, teachers, and school technicians to alter Tux Paint's behaviour using a simple, easy-to-use graphical interface. (It's separate from Tux Paint, to prevent children from changing things.)
9. ... and much more!
