"Barrier-grid animation or picket-fence animation is an animation effect created by moving a striped transparent overlay across an interlaced image." from https://en.wikipedia.org/wiki/Barrier-grid_animation_and_stereography

You've probably seen books by the artist Rufus Butler Seder like Gallop! or Waddle! in which the illusion of a moving picture is created by sliding a piece of clear plastic printed with vertical bars across a background. In this workshop, we will make our own scanimations. All materials provided.

Grades 2+ only, please.
