Just something for that young at heart to play with.....
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 completely free software, released as “Open Source” software, under the provisions of the GNU General Public License (GPL). This means you may download it and install it on as many machines as you wish, copy it for friends and family, and give it to your local schools. In fact, we encourage this!
Tux Paint runs on most systems, but check the Requirements if you're unsure whether your system can support it.
