Xi WARP 1.2

Xi-WARP is a program that allows you to apply distortion to any image simply by drawing two guidelines: the first area that you want to distort the original image, the second to indicate the path to be followed.
And can be applied biases on the same image and animate the entire process.

Autostitch, 2D image stitcher

Although it was only a demo version is fully functional (maybe certain programs like this were called free demo version).
Of all the programs to create landscapes that I know, Autostitch is the easiest and most automatic (though Microsoft ICE is really easy), since he has few options, and you do not need no configure: just put photos in a folder, click Start, and the program automatically creates a panoramic image in JPEG format.
The results are quite good. It 'true that-if you make a little' test-with Hugin you get a better result, but the simplicity of AutoStitch is hardly equal.

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) .
