Take a look at a really fun stick figure animator at http://www.snapfiles.com/get/stickfigure.html

“Pivot Stickfigure Animator is a unique software, that allows you to create stick figure animations easily and without any artistic skills. You can move the sections of the sick figure and easily create a chain of animation frames that can be previewed as you go. You can use more than one stick-figure in the animation, and even create your own stick figures using an easy to use visual editor that lets you assemble objects out of lines and circles. In addition, you can configure animation size, speed and other options. The result can be saved as animated GIF file. Fun and easy to use, surprisingly well featured.”
