Pivot Stickfigure Animator.
It's a free download that makes it ridiculously easy to draw and animate little stick creatures. Here's one I just made. You can click on it to seem him in full-size animated glory. Yes, his name is Howard.
PS: If you get a song with the right beat just right, it will look like he's dancing to it. This was highly amusing at 11:30 pm. (I recommend Harder, Better, Faster, Stronger.)
