TuxPaint, Children's drawing and photo

It an open source graphics/design created especially for children (3 to 12 years), very colorful, friendly and easy to use. The program is very nice (and suitable for a child), and we can hear nice sound effects at the various operations (when we draw is that when we select different instruments). Many brushes with different shapes are ready (including penguins and various forms of cartoons, which may be added to drawings).
Also there are several effects that can be applied to any design or just a part of it, such as relief, lighten/darken, draw rays of light, waves, change colors, etc..
Overall, a program dedicated to children, immediate and richest, but also able to take their familiarity with commands and programs that will use filters in the future (many commands and filters are very similar, whether you use programs for children and professional programs) .
