My 10 year old son downloaded the free "Pivot" stick figure animation program, and I started playing with it this morning. This is my first go at using Pivot, but Max has been animating dramatic fight scenes with Halo guns and characters he created.

As soon as I started making a 'walk,' I turned it into a run, and then I had to smack him off the side of the frame. I kept making the bounces bigger, and for some reason the twitch at the end cracks me up.
