News ... Synfig Studio 0.64.0 for Windows is available now.
Synfig is the best , light and easy way to do an animation.
I used with linux and is simple tool to make animation.
I think this software can be one great educational software.
Your child will leave aside the pencil and sketchpad, watercolors to make own animations.
