From author's site:

An Open Source vector graphics editor, with capabilities similar to Illustrator, CorelDraw, or Xara X, using the W3C standard Scalable Vector Graphics (SVG) file format.

Inkscape supports many advanced SVG features (markers, clones, alpha blending, etc.) and great care is taken in designing a streamlined interface. It is very easy to edit nodes, perform complex path operations, trace bitmaps and much more. We also aim to maintain a thriving user and developer community by using open, community-oriented development.

From author's site:

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.

Kids are presented with a blank canvas and a variety of drawing tools to help them be creative. (See the full list of features.)

From author's site:

A painting package designed to provide a realistic and fun simulation of using paint on a canvas, along with pens, pencils, crayons, and other tools. Attractive interface.

Each of the tools in ArtRage is designed to work like its real world counterpart (minus the smell of paint thinners, and that piece of glitter you just can’t get out of the carpet).

Thick paint smears and blends, pencils and chalks smudge, and markers work just like they do in the real world. Many of the tools can be adjusted to give different effects. You can paint with thinned oils, use wet or dry markers, soften your pencil and control the hardness of the crayon, and much more.
