Each child invented a character. They drew these characters as a "first frame" to begin a sequence within the animation. This character was then passed on to someone else to copy. The copy then passed to someone else to copy the copy. With each copy the drawing changes -- sometimes slightly, sometimes dramatically. By looking at all the drawings from the first to the last you can see the character change and move around the page.
Brendan shot small video files of each drawing in the order that they were made and used iMovie to animate them. You can watch the final piece by following this link:
